Pressure Sensors & Transmitters

Pressure sensors detect, regulate or monitor pressure and convert the input data into an electronic output signal. Gauge pressure sensors measure pressure relative to atmospheric pressure. Absolute pressure sensors measure pressure relative to absolute zero pressure. This allows for very precise measurements. Differential pressure sensors use two different pressure ports and measure the difference between the two.

Pressure transducers convert an applied pressure into a measurable electrical signal that is proportional to the applied pressure. An elastic material inside of a pressure transducer will deform when exposed to a pressurized medium and an electrical device will detect the deformation and convert the result into a usable electrical signal. The electrical signal is not linearized or temperature compensated. Pressure transmitters amplify, linearize and compensate the signal from a pressure transducer and transmit the signal to a remote receiver.

Dwyer Mercoid Series 626 Pressure Transmitters contain a full-scale accuracy (0.25%) piezo-restive sensor in a NEMA 4X (IP66) stainless steel general purpose housing or cast aluminum conduit housing. The Series 628 Pressure Transmitters are ideal for OEMs with 1% full scale accuracy sensors. Both Series 626 and 628 transmitters are corrosion-resistant and are available in absolute and gauge pressure ranges with a variety of optional outputs, process connections and electrical terminations.

APG PT-400 Pressure Transducers are designed for harsh environments, high pressure spikes, high vibrations and extreme temperatures. A Modbus RTU output on the PT-400 pressure transmitter is compatible with any Modbus PLC or controller.

The MLP2 Series Low Differential Pressure transmitters are designed for use in OEM or high-density panel mounting applications. Key installation features include an integral 35 mm Din rail mounting foot, vertically orientated wiring and pressure connections, and a pushbutton zero function conveniently located on the front cover. The MLP2 incorporates a high accuracy, piezo resistive, silicon sensing element which senses differential pressure and provides a linear 4 to 20 mA or DC voltage output equal to the specified pressure range. This technology reduces warmup shift while also reducing the effect of package stress for increased long-term stability.  In addition, the unit contains a de-pluggable terminal block that can be removed for ease of installation. This unit must be ordered with a single uni or bi-directional pressure range and output signal from +/- 0.1” of water column to a maximum pressure of +/- 40” of water column depending on your application. All MLP2 Series pressure transmitters are calibrated using NIST Certified equipment. Optional 3 or 5 point NIST Certificates are available and must be specified when placing your order. Applications: Building and Duct Static Pressure, Filter Monitoring, Air Flow Measurement, Process Control, Roof Top Units, Air Handlers, Clean Rooms, Isolation Rooms, Data Centers.

The DLP Series is based on a piezoresistive, silicon sensing element which senses Differential Pressure and provides an analog output. The hinged cover on the DLP can be easily opened using the integrated locking tab on the side of the enclosure. This allows for easy access to the zero function and ­field selectable ranges and outputs. The DLP Series also includes an optional, ­five-digit LCD for installation and monitoring support. Field selectable analog outputs include 0-5 and 0-10 VDC, or 4-20 mA which correlate to a specifi­c uni or bi-directional pressure range from 0-0.1” up to 0-40” of water column, depending on your model selection. Each unit must be ordered with the specific pressure range needed to meet desired application requirements. Options include a Pitot Tube or Din Rail Clip.
