Pyrowell

Pyrowell is a combination of Infrared Non-contact pyrometer in a housing like a thermocouple. The infrared sensor sits on top of the holding tube, and is connected to the electronics box by a special cable. This system gives an economic, accurate and fast temperature measuring solution for high temperature applications. Pyrowell is a good alternate to Precious metal Thermocouples like Type R, S & B, for high temperature applications. Since the elements are made of Platinum and Rhodium these thermocouples types are very expensive, and are very fragile to shock and vibration. Also, ingress of gases through the protection tube will also effect the accuracy and life of these thermocouples.

Since pyrowell is a non-contact device, it gives trouble free operation for years. The one end closed sighting tube works as a perfect black body hence like other Infrared sensors no need of setting of emissivity. The one end closed tube assures very high accuracy of measurement and has the same installation like a thermocouple.

Pyrowell offers an alternate means of temperature measurement. The system can be field calibrated and the drift is less than 0.5 deg per year, which can be adjusted. The output for Pyrowell can be adjusted in the field to 4-20 mA or thermocouple mV output (equivalent to type R/S/B thermocouple), this provides the flexibility to the customer to change Pyrowell with an existing thermocouple, keeping the same cabling. Pyrowell also offers a digital display, an ON/OFF controller; the digital outputs from the electronic box can be used for datalogging through infrasoft software.
