type csp thermometrics laboratory ntc temperature standards the type csp temperature standards are ultrastable probe thermistors which have been calibrated to an accuracy of 0.01c. the standard unit has a thin, conformal coating of silicone rubber over the entire unit; this makes it suitable for immersion in a water bath. they are also available with stainless steel sensor housings, or they can be encapsulated into various sheaths. see assemblies depicted in the fgure. applications all units can be supplied with calibrations over different temperature ranges, with longer leads; and with various coatings. data two types of csp thermoprobes are stocked for quick delivery: ? the csp60ba252m, with a nominal resistance of 2500 ohms @25c, is furnishedwith calibration over the range of 0 to 50c. ? the csp60bt103m has a nominal resistance of 10k ohms @25c and is furnished with calibration over the range of 0 to 100c. the calibration table normally furnished with the csp60ba252m provides data every 0.25c between 0 and 50c. the table furnished with the csp60bt103m provides data every 0.5c over the range of 0 to 100c. both units are furnished with interpolation equations which are accurate to 0.01c. tables with calibration data furnished every 0.01, 0.05 or 0.1c are also available. a mphenol advanced sensors
