AIMS
AP1655 series converter provide the quality and highly stable components
for measuring the low range values of pressure and are specifically
designed for this.
They employs the latest in semiconductor technology for stfable
performance.
A closed type bridge configuration is provided for electrical connection.
This converter unit also contains a high accuracy Instrumentation
amplifiers with voltage controlled precision references.
State of the art design and trimming small size make it ideally
suited for many applications. The true two-wire configuration allows
signal and power to be supplied on a single wire-pair by modulating
the power supply current with input signal.
Installation, Calibration and Commissioning are simplified by compact
design integral junction box and local zero and span adjustments.
The entire unit is housed in a die-cast aluminium enclosure.
The digital indicator unit provides a 3 digits numeric display of
the respective engineering unit in terms of mmWC. This indicator
incorporates devices like large scale integrated circuits, low drift
opamps, reference zeners, regulators, etc., The entire unit can
be drawn out by removing the screws at the backside. Optionally,
two switches are provided in the front panel to read either the
input or the setpoints (alarm and trip) and the setpoints can be
varied by means of the potentiometer that are provided in the front
panel and their respective relay contact outputs are available at
the rear end of the instrument for the external use.
