TWS SERIES

Independent RH, Temp, and Analog Setpoint Outputs

TWS

All TWS Series institutional grade temperature transmitters are fieldprogrammable and 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 discouraged 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 to 20 mA or 0 to 5/0 to 10 Vdc (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.

Flexibility

Independent heat/cool (TWS relay) or analog setpoint outputs (TWS analog) provide application exibility

LCD display

LCD for local display of readings and setup values…easy visibility under any lighting conditions

Offset function

Offset function adjusts calibration offsets for temperature
