Setra 370 Specifications

Model 370

Digital Pressure Gauge

DESCRIPTION

Setra Systems Model 370 oers extremely high accuracy and un­matched stability in a digital output conguration. Environmental
monitoring and test & measurement systems around the world rely on
Setra’s experience in barometric pressure measurement instrumenta­tion, as well as high accuracy measurements of higher pressures. The
370 utilizes Setra’s unique SETRACERAMTM sensor, which is combined
with advanced microprocessor based circuitry and sophisticated rm­ware to provide system accuracy to better than ±0.02% FS.

The Model 370 Digital Pressure Gauge is an extremely versatile instru­ment. Pressure and altitude data is displayed on a 6 digit LCD and is
also accessible through a bidirectional RS-232 port. A numeric keypad
is provided for easy access to engineering unit conversions, min/max
tracking, entry of Hi/Lo alarm setpoints and calibration procedures.
The 370 is also available with an optional rechargeable battery pack to
bring lab accuracy to the eld.
