GENERAL DESCRIPTION
The Model GP-
200□G is a constant temperature type Pirani Vacuum gauge utilizing the thermal
conduction of gas. The controller and measuring unit being separated from each other, measurement is
less affected by the difference in the sensor head cable length. (No readjustment is requires when the
cable length is changed.)
The display is a large
‐
sized 7-segment digital indicator (red LED) that can be easily read.
The DIN size has been employed and the weight has been reduced considerably from that of the
predecessor models.
M3 terminal block is employed for easy connection with an external control system.
Pressure comparison values can be set at three places. The comparator output is delivered as transistor
output (open collector).
