Pressure transmitters determine the pressures in liquids and gases and convert these pressures to an electrical signal. The PX61 features compact construction, an integral amplifier, large output signal and extensive medium compatibility. The design provides a 1/2% accurate, economical transmitter that can operate accurately over a wide temperature range with corrosion resistance.
The ceramic diaphragm sensing element deflects under pressure. The mechanical deformation is converted to an electrical signal by means of a DMS-bridge. An electronic system converts the DMS-signals to ...
The VIP-9000 is an I/P or V/P transducer for interfacing electronic control panels to pneumatic valves. A 4-20 mA or 2-10 VDC (capable of delivering 20 mA) input signal is converted by the electronics to a 3 to 15 psi pneumatic signal to position dampers and valve actuators.
We have incorporated a very low air consumption industry standard valve with new electronics to provide excellent reliability with flexible voltage or current inputs.
The model WGT-420 differential pressure transducer has been developed primarily for HVAC and similar applications. It converts a differential or gauge air pressure signal to a 4-20 mA signal. It provides higher accuracy at the same cost as the LPTB models it replaces.
The new silicone sensor offers excellent performance characteristics at a low cost. A signal conditioning circuit runs as a two wire 4-20mA device.
The input pressure signals are mechanically dampened to reduce sensitivity to turbulence and short duration pressure fluctuations.
Integral zero and span adjustments are factory calibrated to ...
APPLICATION
The model AFS-22 is a general purpose proving switch designed for HVAC and energy management applications. It may be used to sense positive, negative or differential air pressure.
DESCRIPTION
The plated housing contains a diaphragm, a calibration spring and a snap acting switch.
The sample connections on each side of the diaphragm accept 0.25" O.D. metallic tubing via the integral compression ferrule and nut.
An enclosure cover guards against accidental contact with the live switch terminal screws and the set point adjusting screw. The enclosure cover will accept a 0.5" conduit ...
