INFCDT Differential Temperature Meter

DIFFERENTIAL TEMPERATURE METER
High Performance INFINITY^® Series Meters

INFCDT / INFCDR
Temperature Displayed as T1-T2, T1 or T2
J, K, T or J DIN Thermocouple Input, User Selectable
Optional Programmable Analog Output
Optional Two Form C 6 Amp Relays, Each Relay Independently Assignable to T1, T2 or T1-T2
One-Touch Tuning in Proportional Mode
2, 3 or 4-wire RTD Input (DIN or NIST)

The differential temperature meter is a versatile dual input indicator/controller. The touch of a button toggles the display between T1, T2 and T1-T2. Analog output is optional, and any one of the three values available can be chosen for this output. Dual 5 Amp relays give you the tools for on/off alarm or control. The control outputs can be tied to T1, T2 or T1-T2. The user selects either J, K, T or J DIN thermocouple input from the front panel. The units of measure can be switched between ░C and ░F with the front-panel pushbuttons.

The optional analog output may function as retransmission of temperature or assigned to Setpoint #1 and used as a proportional control output (-011 required). Setpoint #1 will still continue to operate as a setpoint, while the analog output of either 4-20 mA or 0-10 V may be used to proportionally control an external process.
