Resistance Thermometry
Model 5840E2 Secondary Standards Bridge
5840E2 is a new series of high performance resistance thermometry bridges from Tinsley that is unique in offering the latest technology in both AC and DC measurement. Integrity in measurement has always been a hallmark of Tinsley instruments and 5840E2 continues that tradition.
However, now you have an even lower frequency AC bridge, or switched DC measurement technology to choose from, according to your needs.
5840E2 is the first product from Tinsley that is available as an AC Bridge and as a DC instrument enabling you to choose the best suited to your application, or to compliment your existing equipment. The AC bridge now operates at the lower frequency of 25Hz (50Hz supply) or 30Hz where your power supply is 60Hz, while the DC version provides a switched DC sensor current to simulate the advantages of
AC - AC bridges eliminate entirely the errors caused by thermal emf's* in the probe or associated wiring.
5840E2 is easy of use and is versatile in operation. You can choose and save what information you want to display on-screen as an aid to efficient working. You can also choose to select or change functions, such as probe current, by a dedicated switch or from within the menu displayed on screen.
For multi-channel applications, 5840E2 operates with Tinsley's existing switch box systems to allow system expansion to 60 channels.
