DMR30-TC1 Series Thermocouple Temperature Meter PRODUCT OVERVIEW The DMR30-TC1 digital panel meter performs precision temperature measurements when used in conjunction with an external thermocouple. Supported thermocouples include ANSI types J, K, E and T. This meter features a highly visible, 0.45 (11.4mm) high, 5 character+sign alphanumeric LED display which can provide up to 4 digits of measurement resolution. Configuration is made easy by a contactless touch-sensor front-panel user interface, eliminating the need for jumpers, potentiometers, or DIP switches. The meter is powered from an external 9-32VDC supply and typically requires only 40mA when operated at 12V. An isolated solid-state relay can be set to close at user-defined trip-points, providing external signaling capability. The meter features a rugged polycarbonate housing that is mountable in a round hole using the supplied nut and gasket, or by using 3 4-40 (M3) screws. The DMR30-TC1 s features make it ideal for use in laboratory instrumentation, factory automation, and other applications requiring precise temperature monitoring.

Variation in thermocouple sensors used with the meter may significantly increase the total system measurement error. 3) Typical accuracy with meter at 25 C. 4) Characterized against calibrated thermocouple simulator.
