Beede Optemp™ Series Meter Relays

The high performance is due in part to the  built-in, solid state operational amplifier.

There's a rugged, high-torque pivot and jewel movement with non-contacting optical switching for fast response, inherent noise rejection and continuous indication.

Cold junction compensation accuracy for +25ºF to +125ºF (ambient).

Types J and K: 1% of full scale.
Others: accuracy specs depends on application.

Upscale thermocouple break protection is standard.

Recorder output is available.

High impedance input allows small gauge thermocouple runs up to 100 ohms without adjustment.

There's electrical cold junction compensation, thermocouple break protection, and dial scales show both ºF and ºC.

Other Pyrometers built to your requirements:

  • Thermistor input.
  • Platinum, Nickel, Copper RTD's.
  • 2, 3 OR 4 Wire connections.
