Maximum operating temperature:

Output voltage range can be specified to a resolution of

0.1 V. The output will continue to respond to 110% FS. i.e. if a 0

Shunt Calibration

Shunt Calibration provides a customer accessible connection which, when applied, causes a shift in output of 80% FS in order to simulate applied pressure. It is fitted to the mV, Configurable 4-wire and Configurable 3-wire versions as standard. It is not available with DIN, M12 x 1 or M20 x 1.5 electrical connectors (options 7, D, G and R). Shunt calibration is activated in different ways depending on the electrical connector and version:

• mV versions: connect Shunt Cal to -ve Supply or where available, connect both Shunt Cal connections together.

• Configurable 4-wire and Configurable 3-wire versions: connect Shunt Cal to -ve Output or, where available, connect both Shunt Cal connections together.

Note: Not available with reverse output.

Performance Specifications

There are three grades of performance specification: Industrial, Improved and Premium.
