Dwyer 605 Series Magnehelic Differential Pressure Indicating Transmitters

Dwyer 605 Series Magnehelic Differential Pressure Indicating Transmitters

Provides for both visual monitoring and electronic control of very low differential pressure. The 605 Series is ideal for control applications in building HVAC systems where local indication is desired during routine maintenance checks or necessary when trouble shooting the system.


Dwyer 629 Series Wet/Wet Differential Pressure Transmitters

Dwyer 629 Series Wet/Wet Differential Pressure Transmitters

Monitors differential pressure of air and compatible gases and liquids with 0.5% accuracy. The design employs dual pressure sensors converting pressure changes into a standard 4-20 mA output signal for two wire circuits. Small internal volume and minimum moving parts result in exceptional response and reliability.


Dwyer 616W Series Differential Pressure Transmitters

Dwyer 616W Series Differential Pressure Transmitters

Positive, negative and differential pressures can be measured within a full span accuracy of ±0.25. Units are enclosed in a polycarbonate case, rated NEMA 4X (IP66) and operate by sensing the pressure of air and compatible gases then sending a standard 4-20 mA output signal. Design enables operation in 2-wire current loops


Dwyer 636D Series Fixed Range Differential Pressure Transmitters

Dwyer 636D Series Fixed Range Differential Pressure Transmitters

Can be used for measuring pressures of liquids, gases & vapors. All available ranges have 0.5% F.S. accuracy with a 4-20 mA Output standard or optional 1-5V DC output. The NEMA 4 housing is an all 316 welded construction that is designed to withstand the harshest environmental conditions and is compatible with most media.


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 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 DM-2000 Series Differential Pressure Transmitters

Dwyer DM-2000 Series Differential Pressure Transmitters

Senses the pressure of air and compatible gases and sends a standard 4-20 mA output signal. The DM-2000 housing is specifically designed to mount in the same diameter cutout as a standard Magnehelic gauge. A wide range of models are available factory calibrated to specific ranges.


Dwyer ISDP Series Intrinsically Safe Differential Pressure Transmitters

Dwyer ISDP Series Intrinsically Safe Differential Pressure Transmitters

Provides a 4-20 mA process output, a robust NEMA 4X enclosure, plus a large LCD display that can be programmed to read in pressure, velocity or flow. Features security level, English or Metric engineering units, pressure, velocity or flow operation, K-factor, volumetric flow operation, plus many more.


Dwyer 677B Series Differential Pressure Transmitters

Dwyer 677B Series Differential Pressure Transmitters

Designed to measure pressures as low as 0.1"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.


Dwyer 616KD Series Differential Pressure Transmitters

Dwyer 616KD Series Differential Pressure Transmitters

With a single digital push button, both zero and span are calibrated properly, nothing else is required.
