IRCON Inc. introduces its new “56-Series” of Modline 5 sensors specially designed for use in spot weld and induction heat-treating applications. The thermometers are designed to handle the harsh demands of manufacturing environments, incorporating a NEMA 4-rated housing, high-temperature cable and completely sealed electrical connectors and electronics. The line offers Total System Health Check capability, which reviews the infrared detector, electronics and (optionally) the sensor’s window to see if they conform to necessary operating standards.
