Design Features
Hastings Thermocouple Vacuum Gauge Tubes are precision sensing devices designed
to provide maximum accuracy in the measurement and control of vacuum. Fully
compensated for both temperature and rate of temperature change, the tubes
are renowned worldwide for their dependability, and boast a history of success
that has endured for over 40 years. Hastings Gauge Tubes use the rugged but
sensitive, time-tested Hastings thermopile sensor. Short, firmly connected
thermocouples have no suspended weld to an external heater.
Gauge Tube Types
Standard Metal Gauge Tube is constructed of nickel-plated steel with colour-coded
plastic base. Overpressure is 50 psig max.
Glass Gauge Tube is for high temperature and bakeable systems. 10mm (3/8-in.)
O.D. smooth tubulation.
Ruggedised Gauge Tube has a nickel-plated hermetically sealed base with
Monel housing for weather resistance.
Stainless Steel Gauge Tube is for weather-proof, corrosive, or bakeable
applications. Withstands high over-pressurization (consult factory).
VCR Connection Gauge Tube has a female nut connection. 9/16-18 UNF, female
threads with 0.75 hex, Cajon No. SS-4-VCR-3 and No. SS-4-VCR-1.
KF-16 and KF-25 Connection Gauge Tubes available in NW 25 ISO-KF flange
sizes. Simplifies installation while providing a reliable seal.
