Digital Panel Meter for Accurate Current/Voltage Measurement - Model Щ21.7 for Atomic Power Plants

The shield digital electrical measuring device Shch21.7 is designed to measure current or voltage in DC circuits for operation as a part of technical means of nuclear power plants, as well as in other industries. The device can be used in a set with primary converters for measurement of non-electrical quantities, if the ranges of the output electrical signal of primary converters correspond to the ranges of the input signal of the devices. The devices have the following features: selection of input signal measuring range, change of reading range and unit name, programming of indication colour change thresholds of discrete-analogue digital output, data transfer to computing devices via RS485 interface (Modbus RTU, original protocol).

The device is made in a metal case of panel mounting. The mounting structure is designed for installation in a 50 mm thick shield. According to the order it is possible to install the device in a shield of other thickness.
