FEATURES
●
Independent heat/cool (TWS relay) or analog setpoint outputs (TWS analog)
provide application flexibility
● LCD for local display of readings and setup values...easy visibility under any
lighting conditions
● Offset function adjusts calibration offsets for temperature
● Switch selectable 4-20mA or 0-5/0-10VDC analog outputs
● Semiconductor temperature sensor can be field calibrated
DESCRIPTION
All TWS Series institutional grade temperature transmitters are field-programmable
and are designed to satisfy the demanding requirements of pharmaceutical labs,
hospitals, science labs, and other exacting applications. Internal jumpers control
access to a feature which allows field adjustment of calibration offsets. Tampering
can be prevented by setting a jumper to disable keypad program functions.
Analog Output
Analog output models feature a keypad to make adjusting temperature setpoint
values easy. They are unique in reporting the setpoint values back to a control system
by means of 4-20mA or 0-5/0-10VDC (output selected by slide-switch) signals.
Setpoint Relay
The TWS Series setpoint relay models measure temperature and offer thermostat
functionality. Two separate relays can be configured to control heat/cool in
thermostat mode.
APPLICATIONS
● Hospitals and operating rooms, pharmaceutical labs
● Clean rooms
● Food processing plants
●
Environmental testing facilities, and other institutional applications
