DESCRIPTION

All TWS Series institutional grade temperature transmitters are eld-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 eld adjustment of calibration osets. 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 oer thermostat
functionality. Two separate relays can be congured to control heat/cool in
thermostat mode.
