Differential Pressure Transmitters

These transmitters allow professionals to monitor pressure in ducts, rooms, or total building pressure. They give indication of clean room pressures and can be used in a variety of pressure and flow applications. Find a wide selection of these transmitters to fit your application.


Dwyer 645 Series Wet/Wet Differential Pressure Transmitters-

Dwyer 645 Series Wet/Wet Differential Pressure Transmitters

Designed for use with compatible gases and liquids which can be applied to both the pressure and reference ports. Quick response capacitance sensor delivers a 4 to 20 mA output signal proportional to differential pressure with ±.25% accuracy. For ease of installation and maintenance, order optional 3-valve manifold assembly.


Dwyer 647 Series Wet/Wet Differential Pressure Transmitters-

Dwyer 647 Series Wet/Wet Differential Pressure Transmitters

Monitor differential pressure in air/liquid flow systems, HVAC/R automation, pneumatic systems and process control with the Series 647 Wet/Wet Differential Pressure Transmitter. Units are temperature compensated and provide a 4 to 20 mA output signal.


Dwyer 668 Series Differential Pressure Transmitters-

Dwyer 668 Series Differential Pressure Transmitters

Capable of measuring low pressures with a ±1% accuracy - ideally suited for proper building pressurization and air flow control. Can withstand up to 10 psig overpressure with no damage to the unit. Variable capacitance sensor design provides excellent sensitivity and long-term stability. Units also feature reverse-polarity protection.


Dwyer 677B Series Differential Pressure Transmitters-

Dwyer 677B Series Differential Pressure Transmitters

Designed to measure pressures as low as 0.1 in w.c. with ±0.4% accuracy. The transmitter features 15 psid overpressure, reverse polarity protection and EMI/RFI protection. The NEMA 4 housing allows for versatile mounting locations and integral mounting tabs simplify installation.
