The DP26 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, using any of the 3 values
available. The optional control
relays for alarms or on/off control
can be tied to T1, T2 or T1-T2. The
user can select J, K, T or J DIN
thermocouple input from the front
panel. The units of measure can be
switched between °F and °C with
the front panel pushbuttons. The
optional analog output can function
as retransmission of temperature
(assignable to T1, T2, or T1-T2) or
be assigned to setpoint #1 and used
as a proportional control output.
Setpoint #1 will still continue
to operate as a setpoint, while the
analog output of either 4 to 20 mA
or 0 to 10V can be used to
proportionally control an
external process.
