General Information

The PX2670 Series pressure transducers and transmitters sense differential pressure and gage (static) pressure and convert this pressure difference to a proportional high level analog output for both unidirectional and bidirectional pressure ranges. Two versions are offered: the voltage model transducer with 0 to 10 VDC output and the current model transmitter with 4 to 20 mA output.

Environmental Conditions

The PX2670 Series is designed to be operated and stored in the following environmental conditions:

Electrical Connections

Wiring is through a standard PG13.5 cable strain relief. Wiring terminations are identified on the circuit board below the terminal strip (see Figure 1). To access the terminal strip, remove the cover by unscrewing the 2 captive screws on top of the case.

Voltage Models

The voltage model is a 3-wire circuit. The standard voltage model can operate from either 24 VAC or 24 VDC excitation with a 0 to 10 VDC output. The input tolerances are as follows:

24 VAC can operate from 9 to 30 VAC

24 VDC can operate from 12 to 40 VDC
