Description

DigiVac Bullseye Replacement Thermocouple Vacuum Gauge Tube

The DigiVac Bullseye Replacement Thermocouple Vacuum Gauge Tube is an economical replacement sensor designed for vacuum measurement applications where dependable low-cost readings are required. It is an equivalent Type 531 thermocouple vacuum gauge tube and is designed as a replacement for the DigiVac Bullseye Precision Gauge.

This soldered and rugged thermocouple vacuum sensor provides a total measurement range from 0.001 to 760 Torr, with specified accuracy from 0.001 to 6 Torr. Its 1/8" NPT vacuum interface provides a straightforward connection for compatible vacuum systems, while a female-to-KF adapter can be used when an NW/KF interface is required.

The field-replaceable sensor is well suited for OEM applications requiring economical vacuum readings in the 300 to 500 micron pressure range. Common applications include freeze drying, low-pressure distillation, foreline monitoring, and transformer dry-out processes.
