Bridge DC R4053

Also this device can be called: R 4053, R-4053, P4053, P 4053, P-4053.


R4053 DC high impedance bridge is designed to measure the electrical resistance of the dc laboratory and workshop conditions.


Structurally R4053 bridges decorated with two-tone metal body with a sloping panel and designed for operation at the hospital workplace. The body mounted bridge measuring circuit, power supply, electrometer zero indicator to the output device.

High performance measurements of electrical resistance bridge R4053 provided that it contains a built-in power supply (PS) and the null indicator (NI), agreed with the measuring circuits. The null indicator consists of a dynamic electrometer in which to convert the input signal into an alternating current voltage of the capacitor with a large dynamic insulation resistance between the fixed electrodes and the vibrating.


Operating conditions R4053:


Ambient temperature - +10° C to +35° C.

Relative humidity - 80%.

In terms of resistance to mechanical stress R4053 bridges are common.


Counting measurement result in bridges made ​​from R4053 indications numeric values ​​with automatic indication of the position and dimensions of the discharge comma.
