Teledyne Hastings THPS 760

The THPS 760 Plus Vacuum Controller is an
exceptionally stable, accurate and repeatable
absolute pressure gauge that provides
excellent linearity and is unaffected by gas
composition. A full 41⁄2 digit meter indicates
in 0.1 Torr units from 0.1 to 1000.0 Torr.

The heart of this vacum 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.

The THPS 760 Plus is pictured with the HPM-
760S Module. For applications where the
THPM-760+ meter, controller, power supply
functions are not needed, please see PB 108S
for complete technical description of the
HPM-760S.

When exposed to atmosphere, the instrument
measures barometric pressure. Calibration is
simple, no test equipment is necessary, only
an accurate barometric reading is required to
set the high end. The HPS-760 power supply
includes an LED digital readout and two
vacuum alarm relays. Set point pressure is
displayed by pressing corresponding Set
Point Push Button.

The display will immediately
default back to measured pressure when
the switch is released. The two SPDT relays
are rated for 240 VAC maximum at 2A.
