Description
General Description
MDC Thermocouple Gauge Tubes offer a fast and reliable means of measuring vacuum from 0.1 to 1000 micron Hg. They can be read continuously and remotely under severe operating conditions.

Individual thermocouple gauges operate with specific heater current ratings. Gauge tubes must be matched to the instrument's specifications. Refer to the manufacturer's instructions for heater current and thermocouple output. Note that although some units are fitted with eight pins, only four pins are actively used. See tube pin-out configurations below the product table.

UHV Series Tubes feature all-welded construction, stainless steel casings, and are bakeable to 150ºC. Electrical connections are glass insulated. They are offered with Del-Seal™ CF mini-flanges and Cajon VCR® fittings.

HV Series Tubes are supplied with nickel plated steel shell and stem assemblies for corrosion resistance. They are bakeable to 150ºC.

 Tube Interchange / Cross Reference Table
Several of the MDC tubes will directly interchange with models of various manufacturers as noted in the Cross Reference Table. Standard Series tubes are equal or superior in performance while the High Temperature / UHV Series offer even higher specifications. Other models are available on request. Note that although some units are fitted with eight pins, only four pins are actively used.

 Thermocouple Gauge Tube Pin-Out
Generally, for all thermocouple gauge tubes the pin out patterns employ four active pins. Two of the pins supply current to the heater inside the gauge head and two of the pins provide a return signal which is dependent on pressure inside the vacuum vessel. In the case of gauge tubes having eight pins, four of the pins are active and the other four are used for support only.
