PA267 Low Range Differential Pressure Transmitter
PA267 Low Range Differential Pressure Transmitter
Low range differential pressure transmitter.  Ranges 0 - 25, 0 - 50, 0 - 100, 0 - 150, 0- 300, 0 - 500, 0 1000, 0 -1600 and 0 - 2500 Pascals, accuracy +- 1% (optional +- 0.4%) with 4 - 20mA or 0 - 10v outputs.  Can be supplied with optional integral LCD display.  Over range pressure 10psi. Can also be used for flow measurment in ducts using the AV-EP insertion multipoint air velocity probe.

Budget Price: £120 Most ranges available Ex stock

 
Technical overview
The PA267 is designed for overpressure, under pressure, and differential pressure measurements of air and other neutral gases. It is recommended that for applications where control is involved, the high accuracy version is used. The measurement cell uses an advanced design of capacitive ele-ment to ensure excellent linearity and zero stability. The differential pressure to be measures induces a movement of the stainless steel diaphragm which is converted to an electronic output signal by a capacitance measurement and a unique electronic circuit.
  • 2 accuracy levels to suit the application
  • Available in ranges as low as 0-25Pa
  • Overpressure safety margin 10 psi
  • IP65 housing with 20mm cable entry and gland

PA267-LCD Integral LCD option
A ‘duct fixing kit’ is supplied with the PA267 con-sisting of 2m of 6mm ID plastic tubing, 2 x pilot
tubes, 4 x fixing screws.
 		Velocity Measurement:
The PA267 can be used for accurate air velocity meas-urement
in applications such as variable fan speed con-trol in VAV applications. If the BEMS control system is not capable of calculating the velocity from the differ-ential pressure reading (performing a square root extraction) then an IO-VP/AV module can be used to provide a velocity output to the controller.

NB The units are calibrated with the transducer in the vertical position. The zero adjustment may be used to cor-rect any shift in output resulting in mounting the unit other than vertically.
