Sensors & Systems New Infrared Sensor Lets Engineers Check Temperatures with a Smartphone App C alex Electronics Ltd announces the new PyroNFC, a small, low-cost infrared temperature sensor that lets engineers and machine operators use a smartphone app to check temperature measurements on the production line. The PyroNFC sensor measures the temperature of surfaces in industrial processes without contact, and at just 29 mm in length, it is the smallest sensor that Calex has ever produced. It has a linear voltage output for connection to industrial process instrumentation, and an open drain alarm output that can be used simultaneously. By touching an NFC-enabled smartphone against the back of the sensor, the user can read the measured temperature with the free app. The reading updates continuously while the phone is touching the sensor. With the app, the user can also read or write configuration parameters including the emissivity setting, which allows an accurate reading on a variety of materials. There is no need to power the sensor to do this: hundreds of sensors can be configured in minutes on a benchtop without connecting a single wire or cable. As well as being extremely user-friendly, the PyroNFC is also very low in cost. Machine builders will appreciate this, along with its IP65 sealing, compact size and direct linear output for direct connection to instrumentation.
