Digital Temperature Indicator


EK450 is a Digital Temperature Indicator accepting J and K type thermocouples, Pt100 RTDs, millivolt and 4 - 20 mA current input. The large 4½-digit display indicates process temperature. EK450 is accurate to 1% for thermocouples, 0.2% for RTDs and 0.1% for linear (current or voltage) input. The indicator has zero wiring, a very reliable and stable design. It retransmits a 4 - 20 isolated output. Signal isolation protects your devices and machines downstream of our instruments from damaging fluctuations in the input signal. By including input terminals in the excitation loop, EK450 provides power for two-wire 4-20 transmitters.
