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:

Temperature - The PX2670 is designed to operate and be stored with the
following temperature limitations:

Operating: 0 to 150°F (-18 to 65°C)
Storage: -65 to 180 °F (-54 to 82°C)

Position Effect:

Range Zero Offset
0 to .1” WC 2.1% FS
0 to 1” WC .22% FS
0 to 5” WC .14% FS
0 to 30” WC .06% FS

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
