Product Readme |
A:the electric resistance Far EasTone Telecommunications Co., Ltd manometer be applicable to measure and have liquid,steam of decay the function to the steel and the copper metal alloy friendly body etc. lie the pressure of the quality.Because establish a slippery line electric resistance type to send out a machine in the gauge inner part, past can is measure a value with give or get an electric shock the quantity value to spread to keep off measure to order of two gauges up, with realization concentration examination with long-distance leave a control.In addition, this gauge can indicate pressure right on the spot also, in order to in the spot craft check.
Two:main technique index sign
Accuracy grade:1.5
Send out a machine start electric resistance value:3-20 Ωs
Send out a full degree of machine an electric resistance value:340-400 Ωs
Send out the machine connects line to carry the ①② in addition electric voltage to be no bigger than a 6 Vs
The slippery line electric resistance type sends out a machine to connect line diagram.
Connect line diagram with two appearance pressure XMY-10 numeral manifestation instruments and the pressure XMY-12 numerical manifestation control instrument(my plant produce) kit.
Use an environment condition:-40-60 ℃s, the relative humidity is no bigger than 85%, and vibrates and is measure(control) nasty play vein temperature influence of lie the quality:When use the temperature deviated 20 ±s 5 ℃s, its temperature the additional error margin was no bigger than 0.4%/10 ℃ss.Weight:1.2kg .
Three:structure principle
This gauge is sent out a machine by a spring coil tube manometer and a slippery line electric resistance type, etc. constitute.
The function principle of the gauge machine part takes care of a manometer homology with general spring coil.Because the electric resistance sends out a machine to fasten a constitution to spread to move organization in the wheel gear up, so when the wheel gear spreads to move the fan-shaped wheel gear stalk creation in the organization to deflect, electric resistance's sending out a machine to turn arm(the electricity brush) to also correspond ground can deflect, brushing on the resistor to skid because of the electricity, making to be measured the variety transformation of the pressure value as the variety of the electric resistance value, but spread to two gauges up, indicate a correspond of read number.In the meantime, a gauge also indicates to correspond of pressure value.
Four:measure scope
0-0.1;0-0.16;0-0.25;0-0.4;0-0.6;0-1;0-1.6;0-2.5;0-4;0-6;0-10;0-16;0-25;0-40;0-60;-0.1-0;-0.1-0.06;-0.1-0.15;-0.1-0.3;-0.1-0.5;-0.1-0.9;-0.1-1.5;-0.1-2.4.
