1. OVERVIEW
The Model GP-1GRY is a constant temperature type Pirani vacuum gauge utilizing heat conduction of
gas.
If the sensor head burns out, the meter indication will deflect off-scale to the higher pressure side
(atmospheric pressure side).
Pressure can be set at two points by meter relay and the comparator output can be taken out as setpoint
(transfer type).
