Model GM-A
The GM-A is a low cost digital readout that works with amplified (0-5
V or 4-20 mA) transducers or transmitters. This unit supplies power
to the sensors. For use with two wire current transducers, contact factory.
(Separate power supply required for 3-wire use.)
Model GM
The GM is a versatile full function signal conditioner, amplifier and
power supply that works with unamplified mV/V transducers. It also provides
shunt calibration (R-cal) which enables the system to be set up without
using an expensive primary stimulus (done at no extra charge at the
factory if the readout and transducer ar purchased at the same time).
A full range of options like peak/hold, track/hold and dual limits are
available.
Model HM
The HM offers all of the standard features of the GM plus a microprocessor
based factory programming capability. Linearization can improve the
accuracy of a particular transducer. The HM also allows for special
application programming which may be required for certain applications.
(i.e. can make an accelerometer read out in degrees in order to use
it as an inclinometer.) The HM features auto zero, RS-232, and tare
capability.
