2 A Thermocouple Sensor

Product catalog summary

Operating Specifications
The 2A Thermocouple Sensor operates within a range of 1 x 10^-3 to 20 Torr, and the MX2A variant extends from 1 x 10^-4 to 1000 Torr. It features a maximum filament temperature of 250°C and can be mounted in any orientation for pressures up to 20 Torr, but must be vertical for 20 to 1000 Torr. Calibration is done using dry air or nitrogen, with an overpressure limit of 150 PSI. The sensor operates between 0°C and 50°C, with storage temperatures ranging from -40°C to 85°C. The maximum bakeout temperature is 120°C for brass and 200°C for stainless steel. Response time is ≤ 1 second, with varying accuracy depending on the pressure range.

Physical Characteristics
The sensor uses octal male electrical connections and weighs 126 grams. It is constructed from materials such as gold, solder, glass, Alloy 52, 304 stainless steel, nickel, tophet, and cupron.

Ratings and Compliance
The sensor is RoHS compliant.

Description
The 2A thermocouple sensor measures absolute pressure by detecting thermal dissipation. It is available in brass and stainless steel with various fittings. It is compatible with several Televac controllers and active gauges.

Benefits
The sensor is competitively priced, compact, robust, and offers excellent resolution and repeatability. It is designed and manufactured in the USA.

Ordering Information
