PyroCouple - Calex Electronics - #1

Text version of the page

The PyroCouple Series is a range of high quality, low cost, compact sensors which measure the temperature of inaccessible or moving objects and materials. They measure temperatures from -20°C to 500°C, accurately and consistently, with an outstanding response time of 240 ms. PyroCouple sensors are available as either two-wire or four-wire units. Two-wire PyroCouple sensors transmit the target temperature as a 4-20 mA output and offer a simple solution for most non-contact temperature measurement applications. Four-wire PyroCouple sensors transmit the target temperature as a 0-50 mV or thermocouple output (type J, K or T) plus the internal sensor temperature as a 4-20 mA output. This second output can be used to ensure that the sensor is being operated within the correct ambient temperature limits and prevent damage caused by overheating or overcooling. It can also be used to give an approximate indication of the air temperature surrounding the sensor. • Temperature range: -20°C to 500°C • Emissivity setting: fixed at 0.95 • Two-wire 4-20 mA output or four-wire voltage/thermocouple output • Four-wire unit also provides internal sensor temperature • Field of view: 2:1, 15:1 or 30:1 • Fast response with high stability • Stainless steel housing, sealed to IP65 • Quick and easy installation • Optional air/water cooled housing, air purge collar, laser sighting tool and mounting brackets + - - + Display/Controller 4-20mA = Target 4-20mA Temperature Power Supply + - - + 4-20mA = Sensor Temperature Power Supply - + mV/TC = Target Temperature Two-wire units (option 0) Four-wire units (options 1 to 4) OPOP+ PWR+ PWRPWR+ PWRDisplay/ Controller Display/Controller 4-20mA PyroCouple Compact Non-Contact Temperature Sensor with optional Dual Output shown actual size
