8 Channels Thermocouple, LV A/D
TC1
-
A thermocouple is a temperature-measuring device typically consisting of two dissimilar conductors that contact each other at one or more spots. It produces a voltage when the temperature of one of the spots differs from the reference temperature on other parts of the circuit. Thermocouple temperature sensors are widely used for measurement and control, and can also convert a temperature gradient into electricity.

Thermocouple Vacuum Gauge Tubes for Medium Vacuum
DV-6 Series
-
Teledyne Hastings, manufacturer of the original DV-4, DV-5, and DV-6 thermocouple vacuum gauge tubes, produces vacuum measurement equipment with exceptional stability, accuracy, and reliability under the most demanding conditions.The Teledyne Hastings’ DV-6 series thermocouple vacuum gauge tube acts as a localized sensor which is then paired with a selection of meters or controllers to provide reliable, cost-effective measurements in diverse applications. The robust sensor gauge tube is easily installed into vacuum systems and when properly excited, generates a thermoelectric voltage to provide a vacuum pressure measurement based on gas density. The DV-6 thermocouple vacuum gauge tube fully compensates for temperature and rate of temperature change.Thermocouple gauge tubes are calibrated on vacuum systems that contain N2 or Air, but can be used with other gases. Additionally, thermocouple gauges and their controllers can be recalibrated when a replacement thermocouple gauge tube is installed, following instructions in the manual. However, our DB-20 reference tube is available to confirm meter/controller performance. A complete line of installation accessories are also available to simplify the integration of our thermocouple gauge tubes into a variety of vacuum systems. Our goal is to provide “one less thing to worry about”, when performance matters! With a wide range of meter, fitting, relay and output options, the DV-6 series provides a reliable pressure measurement in numerous industries and applications.
