Differential Pressure Transmitters

30 Products
677B Low Pressure DP Transmitter, ± 0.4% Accuracy, NEMA 4 Housing

Differential Pressure Transmitter measure pressures as low as 0.1 in w.c. Applications include variable air volume, environmental pollution control, and building energy management.

DIN Rail Differential Pressure Transmitter, 4-20 mA, 0.1-25 inH2O

DIN Rail Mount Differential Pressure Transmitter senses pressure of air and gases then sends an output signal.

Wet/Wet Differential Pressure Transmitters, ± 0.25% Accuracy, 4-20 mA

The Series 645 Wet/Wet Differential Pressure Transmitters offer high accuracy for gas and liquid applications, ideal for process control and HVAC systems.

Wet-to-Wet Differential Pressure Transmitter, 30 Configurable Options

Differential Pressure Transmitter measures flow of various liquids and gases, pressure drop across filters, and energy management.

Differential Pressure Transmitter, 0-25 inH2O, ± 0.25% Accuracy, NIST Certified

Low Range Differential Pressure Transmitter combine low ranges with stability and reliability. Ultra thin glass clad silicon diaphragm design resists shock and vibration, a drift.

Panel Mount Differential Pressure

Panel Mount Differential Pressure devices help monitor air flow and pressure in buildings, clean rooms, data centers, and HVAC systems for optimal control and safety.

Differential Pressure Transmitter, 0.5% F.S., 4-20 mA, NEMA 4, CSA Approved

Fixed Range Differential Pressure Transmitter is used to measure pressures of liquids, gases, and vapors. This model is designed to withstand the harshest environmental conditions.

Wet to Wet Differential Pressure

Wet to Wet Differential Pressure series offers reliable monitoring for pumps, compressors, filters, heat exchangers, and flow systems.

Rangeable, Wet/Wet Differential High Pressure Transmitters

The PX2310 series is suitable for energy management, process control, liquid level systems, etc. with 4 selectable outputs for ranges from 0-50 to 0-200 psi.

Differential Low Pressure

The Differential Low Pressure series offers reliable measurement for building pressure, filter monitoring, airflow, and process control applications.

Differential Pressure Transmitters

Differential Pressure Transmitters convert pressure difference between two ports into an electrical signal for controls and monitoring. Products in this category span ACI, Omega Engineering, and Dwyer Instruments low differential transmitters for airflow and filter monitoring, panel-mount devices, 4 to 20 mA air and gas transmitters, wet/wet and wet/dry transducers, and compact duct pressure transmitters.

Applications include:

  • Building airflow and duct static pressure control
  • Filter, coil, and fan pressure drop monitoring
  • Cleanroom, data center, and critical room pressure systems
  • Wet/wet, wet/dry, and process differential pressure measurement

Choose by range, media, output, accuracy, mounting, calibration access, and whether the application is low-pressure air or industrial process service.
