Description

The laboratory installation was created on the basis of the “Instruments and methods for measuring pressure” installation (PMSI-08-MCh) as a simplified version.
REQUIRES an external compressor power supply. It is recommended when purchasing several stands of this type with connecting all the stands to an additional compressor simultaneously. COMPRESSOR IS NOT INCLUDED IN THE DELIVERY PACKAGE.
Laboratory installation — desktop version: pressure gauges, pressure sensors and controls are installed on the panel.
Allows you to study means and methods of measuring pressure; gain skills in measuring pressure using dial gauges and pressure sensors of various types; evaluate the error of measurement results.
The installation includes a set of pressure sensors, dial gauges, a receiver, a power supply for pressure sensors, and a multimeter.
 Pressure change range, MPa – from 0+0.005 to 0.4-0.005
 Pressure measurement error, % — 5
 AC power supply:
voltage, V – 220
frequency, Hz – 50
— Overall dimensions no more than, mm – 500*400*500 (length, transverse dimension, height)

Laboratory works:
1. Study of a dial pressure gauge, its principle of operation, determination of the relative measurement error at different pressure levels.
2. Study of a spring-type indicator, its principle of operation, use for assessing pressure levels, determining the relative measurement error at various pressure levels when compared with pressure gauge readings.
3. Study of a pressure sensor with an analog output signal measured using a voltmeter (multimeter), the principle of operation, determination of the relative measurement error when compared with pressure gauge readings.
4. Study of a pressure sensor with a digital output signal, the principle of operation, determination of the relative measurement error when compared with the pressure gauge readings.
