Watlow Solutions To CommonTemperature Sensing Problems

Temperature sensing is a vital part of process using a thermal loop. Sensing product temperatures can eliminate problems, reduce costly down time and waste. Check the list below to see if your temperature sensing can be improved. Contact Sensor Solution • Use a mineral insulated thermocouple assembly• Use a lower mass, 3.2 mm (0.125 in.) O.D. thermocouple assembly • Use a thermocouple assembly with an adjustable compression fitting• Use Teflon
® insulated lead wire where temperature conditions permit• Use RTD sensors• Use a sensor with a molded-on connector• Use mineral insulated, metal-sheath cable • Made-to-order sensors, including; ANSI Types B, C*, E, J, K, N, R, S and T; DIN or JIS calibrated RTDs; positive or negative temperature coefficient thermistors
