Model DTS4050/64Tx, Digital Temperature Scanner, accepts 64 thermocouple inputs. It incorporates RAM, Integral Low Pass Filters, 22 bit A/D converters, and a microprocessor, in a rugged stand alone module. An isothermal block is incorporated for the Uniform Temperature Reference (UTR) for each 64 channel input. NIST thermocouple tables for standard thermocouple types are stored in flash memory. The microprocessor uses these look-up tables to convert mV inputs to Engineering Units. Temperature data are output in °C, °F, °R, K, millivolts and counts.
