The Series PM-THC & PM-RTD 1/8 DIN Temperature Meters, with Jumper-Selectable Thermocouple or RTD Input are designed for various process temperature monitoring and control applications. This PM Series is a versatile product line with a multitude of input and output selections.
PM-THC units can be set to accept J, K, T, E, N, R and S thermocouples each with 2 calibrated ranges in degrees Fahrenheit or Celsius with selectable 1° or 0.1° resolution.
PM-RTD models can accepts four platinum, two nickel and two copper RTD ranges in degrees Fahrenheit or Celsius with adjustable 1°, 0.1° or 0.01° resolution.
Displaying in Rankin or Kelvin can be easily programmed with an offset in the menu. Universal AC or DC power options enable flexibility with usage in various power situations. These meters offer optional 8 A contact or 120 mA solid state relay outputs, plus an analog process signal output with 4 user-selectable current or voltage ranges. To provide a higher level of communication and integration into a system’s network, several communication protocols such as RS-232, RS-485 and even USB options are available. These process meters possess exceptionally quick read rates to 60 conversions per second, while integrating the signal over a full power cycle. This fast read rate feature is ideal for peak or valley capture, on/off setpoint alarm or control applications.
These features and options make the PM-THC & PM-RTD Temperature Meters with Thermocouple or RTD input extremely versatile and able to be utilized in a multitude of temperature monitoring automation applications.
