Terwin u700PT Series
The model μ700PT is a high performance dual channel process indicator/alarm controller, which can
measure and display two process variables simultaneously. A typical application is to use this instrument
with a Terwin 2000 or 5000 series extrusion pressure / temperature transducer which incorporates an
Channel 1 can be configured for process or temperature inputs and the 2nd channel for strain gauge
applications. When used with extrusion melt pressure transducers that employ 6 wire 80% negative shunt
calibration, the μ700PT provides a simple automatic self‐calibration feature for both zero and 80% of the
applicable pressure range.
The μ700PT is provided with two alarm relays as standard and these may be directed to channels 1 or 2 as
required. Both relays may be configured as ‘low’ or ‘high’ with direct or inverse action and two LED
indicators provide relay status. Additionally, delays in the relays action may be introduced (up to 20
seconds) and the relays may be latched with manual reset through the front key pads.
Optional outputs include Modbus / RTU RS‐485 serial communications and user configurable analogue
outputs of 0 – 5V, 0 – 10V, 0 – 20mA or 4 – 20mADC. Also, an optional 24VDC output is available for use with
