The Series PM-THC & PM-RTD 1/8 DIN Temperature Meters are designed for various process temperature monitoring and control applications. These versatile meters support multiple input and output options. The PM-THC units can accept J, K, T, E, N, R, and S thermocouples with selectable resolutions of 1° or 0.1° Fahrenheit or Celsius. The PM-RTD models accommodate platinum, nickel, and copper RTD ranges with adjustable resolutions of 1°, 0.1°, or 0.01°. Displaying in Rankin or Kelvin is also possible.
Peak and valley values are automatically captured and may be displayed via a pushbutton, control signal input, or be transmitted as serial data if a communication option was ordered.
Factory calibrated over the entire sensor range for thermocouple types J, K, T, E, N, R, S (PM-THC); RTD types Pt 100 Ω, Ni 120 Ω, Cu 10 Ω (PM-RTD).
When panel mounted, NEMA 4X (IP65) front cover protection keeps fluids out; enables installation in environments exposed to wash-downs.
Universal power range of 85-264 V ac / 90-300 V dc or 10-48 V dc / 12-32 V ac power eliminates need to purchase country specific models.
Analog signal option provides: 4-20 mA, 0-20 mA, 0-10 V or -10 V to +10 V outputs.
Choice of 2 relays or 2 solid state relays.
Serial data communication of either USB, RS485 or RS232.
High read rates at up to 60 or 50 conversions per second.
PM-RTD possesses flexible 2, 3 or 4 wire RTD connection capability, allowing usage in any existing wiring setups.
Digital filtering is menu-selectable for electrically noisy environments.
Selectable resolutions in Celsius, Fahrenheit, Kelvin or Rankin: PM-THC 1° or 0.1°; PM-RTD 1°, 0.1° or 0.01°.
Bright, red 5 digit LED display.
