1.2 Description
The MV2A is a thermocouple vacuum sensor controller with a range of 1 × 10−3Torr to 20 Torr. It
utilizes a Televac thermocouple vacuum sensor, part number 2-2100-10 or 2-2126-0YY. It has a red,
three-digit, seven segment LED display that displays pressure in units of mTorr and Torr. The MV2A
has 2 set points relays, and a 0-5 Volt analog output.
