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.
Case: Nylon, standard colours black or white, other colours on request.
Fixing system: moulded-in elastic tabs; metal bracket on request (TRS 40
PS).
Glass cover: shatterproof metacrylate ester. Capillaries: bare or coated
copper (black PVC on instruments for heating applications, white
polypropylene for refrigeration); standard lengths 0,5 - 1 - 1,5 metres,
other lengths on request.
Hydrometer fitting: brass, look the table, special fitting on drawing.
Manometer movement: copper alloy Bourdon type "C" spring;
high-sensitivity amplification mechanism in watchmaker’s brass.
Dial: printed aluminium. Custom designed dials may be supplied.
Pressure scales: 0/4 or 0/6 bar.Other scales on request.
Accuracy: ?3% of highest value.

ACCESSORIES
Brackets: as specified, most of the instruments may be supplied, on
request, with metal fixing brackets suitable for the dimensios of the
instrument concerned.
Sheaths: brass fitting, copper pipe (brass on high pressure sheaths).
Besides the standard versions illustrated here, custom designed sheaths
may also be supplied.
Check valves for capillary hydrometers and themohydrometers: allow the
instrument to be removed from the appliance without having to drain the
system. |
