Ratiometer shield LM-08
Also this device may be referred to: LM 08, LM08.
LM-08 ratiometer shield is a showing magnetic system device and is used as a secondary device in combination with resistance thermometers to measure temperature.
Dimensions - 110×110×200 mm.
Accuracy class - 2,0.
Magnetic system LM-08 consists of a permanent magnet pole pieces and a cylinder. The principle of operation is based on measuring ratiometer ratio of current in circuits and constant resistance thermometer. The movable part of the device comprises two frames arranged in a magnetic field. Equilibrium position of the movable part ratiometer depends on the current strength within, which in turn depends on the resistance thermometer.
Measuring range - from -50° C to +50° C.
Nominal static characteristic conversion - Gr.23:
- at a temperature of -50° C - 41,71;
- at a temperature of 0° C - 53,00;
- at a temperature of +50° C - 64,29.
Ratiometer voltage - 127 V.
Operating position of LM-08 - vertical.
Display type - an arrow.
Weight LM-08 - 2,670 kg.
Ratiometer LM-08 certified and listed in the State Register of measuring instruments. The devices comply with requirements of the applicable technical specifications under normal use, transportation and storage.
