This Teledyne-Hastings DV-23 1/8" NPT thermocouple (TC) vacuum gauge tube measures pressure between 0.001 and 5 Torr (1 to 5000 mTorr) and calibrated for clean, dry air or nitrogen. DV-23 series gauge tubes are used with the now obsolete Teledyne-Hastings V-3 and CVH-23 units (not included). These inexpensive sensors are used as ‘rough’ indicators to monitor mechanical pump vacuum levels and to signal when crossover (to high-vacuum) pressure has been reached. Gauge controller recalibration is not required when gauge tubes are replaced. Teledyne-Hastings DV-23 gauge tubes use a rugged, but sensitive noble metal thermocouple and corrosion resistant stainless steel and nickel plated components. They are temperature and temperature change-rate compensated, making them well suited for ambient installations. Standard DV-23 gauge tubes are rated for a maximum temperature of 100° C.
