Digital Thermometer with Thermistor Probe

DMR20-1-TMP-R-C
Series Headline AC or DC Powered Digital Thermometer with Thermistor Sensor
Series Description

Murata Power Solutions’ new DMR20-1-TMP thermistor-input thermometer modules provide a simple cost-effective way to accurately measure air temperatures from -40 to +221°F (-40 to +105°C). The user can choose between Celsius or Fahrenheit readings via a rear pc-board jumper. Each thermometer is supplied with an epoxy-dipped NTC thermistor probe and is factory-calibrated to a typical accuracy of ±1°F. The probe features 18 inch (46cm) long leads to allow for remote installation.

Operating power can be from either 24Vac (50/60Hz) or 6 to 50V DC supplies. Two display-brightness levels are provided to ensure optimal readability under various ambient lighting environments. Typical power consumption from a 12 or 24Vdc supply is 3mA in the low brightness setting, and 5mA in the high-brightness setting. A built-in resettable fuse assures long term reliability, and all units are reverse polarity protected to -75Vdc.

Their large, 0.30 in./7.6mm, bright LED displays can be easily read from 10 feet away (3 meters). Visual indications alert the user to over / under temperature conditions, as well as an open or shorted thermistor. DMR20-1-TMP thermometers employ a precision 0.2% voltage reference and metal-fi lm resistors to achieve outstanding performance over an operating ambient temperature range of –25 to +60°C. The DMR20-1-TMP features a round polycarbonate housing that provides excellent protection against moisture, dust, shock and vibration. The supplied hardware is designed to provide moisture ingress protection to IP67/NEMA 6. Panel installation is straightforward: using available tooling, punch a 1.2 inch (30.5mm) diameter hole, insert the thermometer and gasket into the panel, and securely fasten using the supplied plastic hex nut.
