OMEGA’s new universal panel meter DP20 delivers high performance in a 1/8 DIN size for panel mount, and integration in a wide range of applications. The DP20 accepts universal inputs, including thermocouple, RTD, process (mA & Vdc), resistance, and true RMS voltage and current. By configuration, it will work as an AC and DC voltmeter (up to 600 V) and AC and DC ammeter (up to 5 A) offering application flexibility for process control and industrial requirements. A single universal power supply 18 to 265 Vac/dc allows this unit to be suited for global use.
The optional relays, analog output, and Modbus® RTU serial communications provide customization, control and communication capability. Additional features of the economical DP20 panel meter include scaling, IP65 protection, and programmable decimal points.

Industrial automation systems are expensive assets, designed to offer reliable performance for years. Typically, industrial systems last for decades. It is impractical than to discard these existing systems when new technology becomes available.
So, how do businesses remain competitive and efficient if they cannot afford to adopt new technology? The scenario is common today for most industrial setups...
Temperature can be measured via a diverse array of sensors. All of them infer temperature by sensing some change in a physical characteristic. Six types with which the engineer is likely to come into contact are: thermocouples, resistive temperature devices (RTDs Pt100 and thermistors), infrared radiators, bimetallic devices, liquid expansion devices, and change-of-state devices.
Choose the right temperature measurement instrument for your application...
