DMP320 Descripción general
What is a pressure transmitter? A pressure transmitter is an industrial sensor that converts an applied pressure into a standardized electrical output (commonly 4–20 mA, 0–10 V, or a digital bus signal). Within the sensor hierarchy, the DMP320 sits in the precision-and-dynamic-measurement category, above static process transmitters and below research-grade pressure scanners. Its high-speed signal chain allows pressure curves, peaks, and hydraulic spikes to be recorded with high fidelity, which sets it apart from slower industrial loop-powered devices.
Key features of the DMP320 include: ≤0.5 ms response time enabling capture of transient pressure events; 10 kHz internal sampling rate for fine-grained waveform reconstruction; wide pressure envelope (0…100 mbar to 0…600 bar) for both vacuum and high-pressure service; stainless-steel wetted parts for media compatibility; digital signal processing of the sensor signal by newly developed electronics; and configurable output suitable for industrial automation.
Architecturally, the DMP320 uses a piezoresistive or thin-film stainless-steel measuring cell whose millivolt output is digitized and conditioned by a digital electronics module. The 10 kHz oversampling paired with sub-millisecond analog output update allows the device to track pressure peaks that conventional 1–2 Hz process transmitters miss entirely. This combination is critical for hydraulic testing, fuel-injection diagnostics, and dynamic pressure profiling.
Typical applications include fast hydraulic pressure monitoring in test rigs and mobile hydraulics, peak pressure detection in fuel-injection and combustion test benches, dynamic profiling of HVAC/R and process pressures, and laboratory instrumentation where pressure curves, peaks, and hits must be measured exactly. The stainless-steel construction also supports chemically aggressive media under the medium temperature envelope.
When designing with the DMP320, observe the medium temperature limits (typically -40 to 125 °C depending on version) and the electronics operating temperature range; derate the mounting configuration accordingly. Never insert pointed tools or direct compressed-air jets against the sensitive measuring diaphragm, as permanent deformation of the diaphragm will permanently corrupt calibration and accuracy. Verify cable gland sealing for the installation environment.

Aplicaciones típicas
DMP320 es adecuado para 6 aplicacións: Hydraulic Test Bench Dynamic Pressure Profiling, Fuel Injection Peak Pressure Detection, HVAC/R and Refrigeration Process Pressure Monitoring, Pneumatic System Peak Pressure Detection, Laboratory Pressure Curve Analysis, Mobile Hydraulics and Heavy Equipment Diagnostics.
Hydraulic Test Bench Dynamic Pressure Profiling
The DMP320's ≤0.5 ms response time and 10 kHz sampling rate make it ideal for hydraulic test bench pressure profiling, where shock spikes, valve-closure transients, and pump ripple must be recorded with high fidelity. In this application the transmitter captures pressure curves, peaks, and hits exactly - events that a conventional 1-2 Hz process transmitter would miss or alias. The stainless-steel wetted parts handle hydraulic oils within the -40 to +125 °C medium envelope, and the configurable output (4-20 mA, 0-10 V, or digital) integrates directly with DAQ systems. Engineers typically mount the DMP320 in line with a pressure snubber to protect against sustained overpressure spikes common in hydraulic test rigs.
Recomendado
Fuel Injection Peak Pressure Detection
Fuel-injection diagnostic stands require a pressure transmitter that can resolve the rapid pressure rise during injector opening and the subsequent ringdown oscillation. The DMP320's sub-millisecond response time and 10 kHz sampling rate capture injector opening transients and combustion-chamber pressure peaks with sufficient bandwidth for waveform analysis, supporting fuel-injection research, common-rail diagnostics, and injector production-line testing. The 0…100 mbar to 0…600 bar range envelope covers low-pressure fuel-lift lines up to high-pressure common-rail systems, and the stainless-steel measuring cell tolerates diesel and biodiesel media within the rated temperature envelope.
Recomendado
HVAC/R and Refrigeration Process Pressure Monitoring
In HVAC/R and refrigeration systems, the DMP320 enables fast-acting suction and discharge pressure monitoring for compressor diagnostics, expansion-valve tuning, and refrigerant-cycle research. Its 10 kHz sampling reveals valve-induced pressure oscillations and compressor pulsations that legacy transmitters alias, supporting lab characterization of inverter-driven compressors and electronic expansion valves. The wide -40 to +125 °C medium envelope covers standard HFC, HFO, and natural refrigerants, and the stainless-steel construction tolerates refrigerant oils and common lubricants used in commercial refrigeration.
Recomendado
Pneumatic System Peak Pressure Detection
Pneumatic systems exhibit fast transients during valve closure (water-hammer-equivalent effects in compressed air lines) and during actuator cycling. The DMP320's ≤0.5 ms response captures these events with sufficient fidelity for pneumatic-test bench validation, actuator tuning, and compressed-air distribution diagnostics. The 0…100 mbar low end suits vacuum and low-pressure pneumatic measurements, while the upper range covers shop-air and industrial pneumatic pressures within the medium-temperature envelope. Stainless-steel wetted parts tolerate dry and lubricated shop air and common pneumatic oils.
Recomendado
Laboratory Pressure Curve Analysis
Research laboratories and calibration houses use the DMP320 to record pressure curves, peaks, and hits exactly during material testing, gas-law experiments, and dynamic-pressure calibration of other instruments. The 10 kHz internal sampling rate paired with a sub-millisecond analog update makes it a high-bandwidth reference for characterizing slower transmitters and verifying dead-weight tester transient performance. The wide 0…100 mbar to 0…600 bar envelope and stainless-steel construction support laboratory gas and liquid media across most common research setups, while the digital signal processing simplifies data acquisition and post-processing.
Recomendado
Mobile Hydraulics and Heavy Equipment Diagnostics
Mobile hydraulic equipment - construction machines, agricultural vehicles, and forestry equipment - exposes pressure transmitters to harsh vibration, temperature swing, and fast hydraulic transients. The DMP320 with its stainless-steel housing, wide temperature envelope, and sub-millisecond response time captures loader-arm hydraulic transients, brake-system pressure peaks, and implement-circuit dynamics for diagnostics and predictive maintenance. The configurable output (4-20 mA, 0-10 V, or digital bus) interfaces with both legacy CAN-based telematics and modern data loggers. Mount the transmitter with a snubber to protect against sustained overpressure spikes.

Notas de diseño
Never insert pointed mechanical tools or direct compressed-air streams against the sensitive measuring diaphragm. The diaphragm is a precision-formed stainless-steel element whose geometry defines the calibration; permanent deformation from impact or abrasive cleaning will permanently corrupt the accuracy class. Use soft brushes and approved cleaning media only, and never exceed the nominal pressure range - even briefly. If an overpressure event is suspected, return the unit to the manufacturer for inspection rather than continuing to use it.
The medium temperature limit is -40 to +125 °C, but the electronics operating range is -40 to +85 °C. For sustained high-temperature media, the stainless body conducts heat to the electronics; mount a cooling neck (pulse piping) or use a remote diaphragm seal to keep the electronics within its envelope. Verify cable gland temperature rating at the electronics side - many cable gland materials are limited to 85 °C and will fail above that, breaching the IP rating.
Although the DMP320 is a wired industrial transmitter and not a PCB component, the signal-conditioning cabinet still requires best-practice wiring: shielded twisted pair for the 4-20 mA loop, separate cable tray from power lines to avoid EMI coupling, and proper grounding at the cabinet end only (avoid ground loops). For 0-10 V and digital variants, follow the BD|SENSORS datasheet wiring diagram exactly - reversed polarity on a 2-wire 4-20 mA loop can damage the loop electronics and is not covered by warranty.
Mount the DMP320 as close to the measurement point as practical to minimize lag from the connecting tubing. Long impulse lines act as low-pass filters and will attenuate the very pressure peaks the transmitter is designed to capture; a pressure snubber at the process connection protects against sustained overpressure while the short impulse line preserves the dynamic response. Avoid mounting the transmitter in a high-vibration location without mechanical isolation - vibration can add noise to the output and accelerate fatigue of the process connection.
Información de cumplimiento
Compliance data not present in the verified web excerpts; BD|SENSORS industrial pressure transmitters are typically RoHS and REACH compliant per the manufacturer's product page, but the specific declaration for DMP320 must be verified against the manufacturer's compliance certificate before procurement. As of 2026-10-14 the specific compliance facts are pending datasheet verification.
