TEMPERATURE METER / CONTROLLER
PANEL METERS/CONTROLLERS
The unparalled accuracy of the NEWPORT®
Electronics INFINITY® signal conditioning
is available in an economical series of Panel Meter/Controllers.
The NEWPORT INFINITY® "C" series
of meter/controllers feature a four digital display plus
optional dual 5 amp Form C relays and a choice of isolated
or non-isolated analog output. The scalable 0-10 Vdc,
0-20mA, or 4-20 mA analog output can be used a retransmission
of the display value or as a proportional control output
as required. The microprocessor based INFINITY®
"C" series includes instruments for Process
(DC voltage and current) Strain Gage, Thermocouple, RTD,
Dual/Differential Thermocouple, Dual/Differential RTD,
pH, ORP.
The INFCRP
accepts 3-wire 100 ohm platinum RTD inputs (alpha = 0.00385)
and has an accuracy of ±0.5°C. Relay models offer the choice
of linear or proportional analog output.
