China used factory equipment differential pressure transmitters
Description of 3051 pressure transmitters of instrument :
MT-3051HP High static pressure transmitter is a differential pressure transmitter suitable for high-pressure device petrochemical and power plants, because of its high pressure 32MPa, and can withstand a one-way pressure overload without damage, so they can reliable high-pressure system for differential pressure measurement.
Technical parameters of 3051 pressure transmitters of instrument :
1 Output signal: digital signal superimposed on the 4 ~ 20MA.DC wire ( analog ) two-wire 4 ~ 20mA DC signal from the user to select a linear or square root output. ( Smart )
2 Power supply : 12 ~ 45V.DC
3 Range ratio : 10:1 or 100 to 1
4 Power Supply Effect : <0.005 % of output span / V
5 Load effect: when the power supply is stable , no loading effects .
6 Accuracy: adjustment range ± 0.1%, ± 0.2% ( standard accuracy of ± 0.2%,)
7 Migration Characteristics: maximum positive migration maximum negative migration of 500% to 600%
Note: a. negative absolute value of the migration of not more than one project at atmospheric pressure .
b. After migrating upper or lower absolute value should not exceed the maximum upper limit of the measuring range .
c. differential pressure flow transmitter migration would undermine prescribing features , it can not be migrated.
d. absolute pressure transmitter can not be negative migration.
8 Damping: adjustable typically between 0.1 to 16 seconds .
9 Start-up time : < 2 seconds , without preheating
10 Working environment: Temperature -29 ~ 93 °C ( analog amplifier ) -29 ~ 75 °C ( digital / smart amplifier ) -29 ~ 65 °C ( with display header )
11 Humidity 0 ~ 95%
12 Protection features: IP65 protection
13 Type of protection : flameproof Exd II BT4-6 Intrinsically Safe Exia II CT5
14 Static pressure effect: Zero error : ± 0.5% max range limits in the pipeline for 32MPa pressure given by the zero calibration .
15 Electromagnetic radiation : 0.05% maximum scale value , receiving radiation frequency 27 ~ 500MHz, Proving Ground strong 3V / m.
16 Instruction sheet ( % ) : LCD digital display accuracy of ± 0.2%
17 Vibration: 200Hz vibration in any direction , ± 0.05% / g.
18 Installation position: vertical diaphragm is not installed , it may produce less than 0.24KPa zero error , but can be corrected by zero .
Weight : 3.9Kg ( excluding accessories )
