760 Plus ™ Vacuum Controller
The 760 Plus (Model HPM-760) Vacuum Controller is an exceptionally stable, accurate, repeatable absolute pressure gauge that provides excellent linearity and is unaffected by gas composition. A full 4-digit meter indicates in 0.1 Torr units from 0.1 to 999.9 Torr.

The heart of this vacuum controller is the HPM-760S module, a stainless steel measurement volume attached to a small and rugged piezo-resistive transducer on a silicon chip. The chip includes a sealed vacuum reference, a resistive bridge circuit, and a temperature compensation network which provides outstanding accuracy and stability.

When exposed to atmosphere, the instrument measures barometric pressure. Calibration is simple, no test equipment is necessary, only an accurate barometric reading is necessary to set the high end. The HPM-760 power supply includes an LED digital readout and two vacuum alarm relays. Set point pressure is displayed by pressing the up or down arrows. The display will default to measure pressure after approximately 15 seconds. The two SPST relays are rated for 230 VAC max. at 5 amps and can be set to activate on either increasing or decreasing pressure.

Installation Accessories
Hastings Instruments offers a complete line of system attachments allowing for easy maintenance and contamination resistance operations. Gauge tubes are offered with various system fittings to match almost any system attachment requirement. Additionally, Hastings’ complete line of quick disconnect attachments allows customers to install these special fittings once and then easily replace sensors without vacuum sealant or tape. For particularly dirty systems, Hastings offers a particle drop-out trap containing a series of nine separate baffles which prevent solid contaminants from having a direct path to the sensors thermopile.
