Features

Mini-Convectron® Sensor Technology

Mini-Convectron® sensors are a unique variation of thermal conductivity gauges where pressure measurement is based on the rate of heat loss from a sensor wire. Unlike traditional thermocouple and Pirani gauges that use only conductive heat loss, Convectron gauges take advantage of heat loss due to convection at higher pressures. This extends the range of accurate, repeatable measurement to atmosphere.

Digital Display Version

Display Side (Analog shown)

The digital display option provides an easy-to-read, 3-digit green LED display that automatically adjusts between two ranges (Torr and mTorr or kPa and Pa).

Digital Interface Version

Parameter Adjustment Side (DeviceNet shown)

Versions with digital communications provides RS485 or DeviceNet interface for easy compatibility with computer controlled processes.

Analog Output

The provided analog output is non-linear 0.375 to 5.659 VDC for 0 to 1000 Torr of N2. 11.5 to 26.5 VDC, 1.6 W max is required to power the 275 Mini-Convectron® vacuum pressure transducer.
