Comby transducer case 40, Indicator gauge and electric output

COMBY
TRANSDUCER CASE

INDICATOR GAUGE AND ELECTRIC OUTPUT

Presentation
The capillary pressure gauge (Hydrometer) in object is equipped of one double functionality. Externally you can see it like a common mechanical index pressure gauge. Inner electrical worker is equipped of an optical system of conversion of the pressure in voltage.
Advantages
Low cost.
Easy of use.
Duration and stability.
Absence of frictions.
Description.
From the outline visible electrical worker in the photo you can see the easy of use of such transducer. In order to use the sensor two resistances of polarization are sufficient as indicated from the electric draw, the Output voltage is present to the heads of the resistance R2. The sensor must be fed with a voltage stabilized of 5 Vcc, present normally on all the electronic cards. The two resistances normally are calculated for one voltage of power supply of the sensor of 5 Volt and one scale of output of 0-1000mV. Various output voltages and scales are easy to calculate or can be demanded to technical office of CEWAL.
