SERIES 3001/3004 NON-HERMETIC THERMOSTATS Typical Applications: Computers Office Equipment Blood Analyzers The Series 3001/3004 thermostat offers tight tolerances for applications that require precision control from a low profile device. These reliable, non-hermetic thermostats maintain the same high degree of quality and performance that character- ize all Elmwood Sensors precision thermostats. The 3001/3004 are factory pre-set, single-pole, single-throw thermal switches available to open and close on temperature rise. Its phenolic base is made dust proof by a metal closure which also provides thermal and electrical isolation for the silver contacts. The low-silhouette design of the 3001 makes it an excellent choice where a non-hermetic precision unit is required for tight tolerances. Model 3001U is similar to the 3001, but manufactured and tested for applications that require a UL and/or CSA rating. The 3004 differs from the 3001 by offering a metal sleeve insert-rivet construction and higher spacing to meet European approval agencies requirements. It is also UL recognized and CSA certified. To insure that a safe combination of thermostat and application is achieved, the purchaser must determine product suitability for their individual requirements. 18 Riveted Insert Sleeve Construction (3004 Only) Rivet Phenolic Base wo ~~ _ Termipal ~~ Metal Sleeve Insert .

The operating temperature ranges include tolerances. The + tolerances shown have been established after careful review of many thermostat applications. Attempts should be made to establish the widest acceptable tolerance possible, For example, the chart may list a tolerance of 5F (42.8C); however, +6F (#3.3C) may be acceptable for the application at reduced cost. Note: Temperature checking methods may be slightly different, and allowance for a 1.8F (1C) variance should be considered.
