JJG 951-2000 Analogue Temperature Indicators and Controllers
Abstract
This procedure is applicable to the initial verification, subsequent verification, and in-use inspection of analog temperature indicators and indicating regulators equipped with thermocouples or resistance thermometers; it is also applicable to the verification of analog indicators and indicating regulators that use DC voltage, current, and resistance as analog electrical signal inputs to reflect other physical variables.
Analog temperature indicators and indicating regulators (hereinafter referred to as instruments) include instruments that do not perform linearization processing on input electrical signals, as well as instruments that perform linearization processing on input electrical signals to make the scale equally graduated (such as instruments with light bar indications and pointer instruments with linear scales). These instruments can be desktop, panel-mounted, or portable.
