Description
Technical field:
The present invention relates to pressure tool technical field, relate in particular to a kind of novel pressure unit.
Background technology:
Pressure unit is the pressure transducer that is output as standard signal, pressure unit in general sense is mainly comprised of load cell, metering circuit and process web member three parts, the physical pressure parameters such as the gas that it can be experienced load cell, liquid are transformed into the electric signal of standard, and to supply with, the secondary instruments such as indicator alarm, registering instrument, regulator are measured, indication and procedure regulation; Pressure unit can be divided into three kinds, general pressure unit, differential pressure transmitter and negative pressure transformer according to measurement range, existing pressure unit all adopts stainless steel to make, volume is large, Heavy Weight, complex structure, is used inconvenience, and temperature stability is not high, easily be subject to the impact that medium bubbles and deposits, the scope of application is extensive not.
Summary of the invention:
The object of this invention is to provide a kind of novel pressure unit, it is simple in structure, good looking appearance, and volume is little, lightweight, easy to use, temperature stability is high, there is very strong wear-resistant and shock proof characteristic, be not vulnerable to the impact that medium bubbles and deposits, applied widely.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it is comprised of body 1, pressure display instrument table 2, electrical connection mouth 3, electric plug 4, sensor 5, O-ring seal 6, process jointing 7, throttling valve 8; The middle part of body 1 is provided with pressure display instrument table 2, upper end one side of body 1 is provided with electrical connection mouth 3, the upper end opposite side of body 1 is provided with electric plug 4, the lower end of body 1 is provided with sensor 5, the bottom of sensor 5 is provided with O-ring seal 6, sensor 5 is arranged in process jointing 7, and the lower end of process jointing 7 is provided with throttling valve 8.
Described body 1 adopts dry type ceramic material to make, and has corrosion resistance.
The present invention in use, is connected with registering instrument 9 by electrical connection mouth 3, and registering instrument 9 is connected with direct supply 10, direct supply 10 is connected with indicator 11, indicator 11 is connected with reometer 12, and reometer 12 is connected with electrical connection mouth 3, and pressure display instrument table 2 is connected with on-the-spot indicator gauge.
The present invention is two-wire system transmission mode, rated power supply is 24VDC, maximum operating voltage≤36VDC, the summation that forms distributor, pull-up resistor and contact resistance in loop, should be in the workspace shown in transmitter load characteristic figure, except the all-in resistance in loop, during for long line transmission, also should consider total electric leakage of wire, under any circumstance total leakage current of wire should be less than 0.1% of full scale to 0.25% grade of transmitter, in the place being easily disturbed, should use shielding line, shielding line is connected with the housing of transmitter.
The present invention is simple in structure, good looking appearance, and volume is little, lightweight, easy to use, and temperature stability is high, has very strong wear-resistant and shock proof characteristic, is not vulnerable to the impact that medium bubbles and deposits, applied widely.
