Low Range Differential Air Pressure Sensors

A multi-point air velocity system using the PA267 differential pressure sensor and AV-EP or AV-MPS air velocity probes. This system can be used to ensure that recommended flow rates for public buildings and industrial plant are achieved. Suitable for flow ranges of 0 - 40m/s.

The DPT-R8 is an electronic differential pressure transmitter with eight jumper selectable measurement ranges in one device, from +/-100PA up to 0-7000Pa. The output is selectable as 4-20mA or 0-10V. The units also have the option of an LCD or Auto Zero function.

The PS series switches are a cost effective solution for various applications in building automation systems in the HVAC/R industry. The PS series sensor include a field adjustable dial with switching ranges from 20-200 pascals up to 500-4500 pascals and maximum pressure of 50kPa. Switching contacts are rates to 3 amps @ 250vAC, allowing the switch to be used for alarming, or to operate fan motors to maintain pressure or flow ranges. The PS switch is a simple mechanical differential pressure switch which can be used for fan, blower and filter monitoring, clean room pressure monitoring, or valve and damper monitoring.

The PA-DPS range of differential air pressure switches are suitable for low differential pressure switching applications. These units are ideal for providing indication of fan status or filter dirty conditions in air, non-combustible, non-aggressive gases in air conditioning and ventilating installations. Adjustment ranges are available from 20 Pa up to 2,000 Pa with a max operating pressure of 5,000 Pa. The switching knob is mounted under the cover to avoid tampering and the scale is individually laser etched for high accuracy. Units are available in standard IP54 or optional IP65 housings and come complete with a Duct Fixing Kit including 2m of tubing, two pitot tubes and fixing screws.

The PA-699 is a differential pressure sensor incorporating a proved ceramic fulcrum lever technology. They deliver calibrated, temperature-compensated sensor signals, available as standard voltage or current outputs. They are ideal for registering low air flow in air conditioning systems and for the measurement of fine pressures in environmental, laboratory and clean room application (air and non corrosive gases).

The 9200 Series meters are a range of compact, general purpose differential pressure meter designed specifically for monitoring low range differential pressures using 4mm tubing to barbed stainless steel connectors on the handheld meter.

The ManoAir100 digital micromanometers are suitable for measuring low range differential pressures of dry air and inert gases. Pressure readings are available in Pa, kPa, mBar or mmH2O and flow readings in m/s for flow velocity of gaseous media can also be displayed based on differential pressures using pitot tubes. Min, max and average readings available. Sets are available with pitot tubes, filters, 1.5m hoses, power supply and carrying case.

The versatile differential pressure Micromanometer ManoAir600 displays Pa, mbar and mmH2O for pressure as well as the flow velocity of gaseous media. Thereby media temperature, effective ambient pressure and humidity are considered.
