Product details


1151GP type transmitter has a very rich variety, which can accurately measure the micro differential pressure to the big differential pressure, low pressure, high pressure, liquid level, vacuum degree and specific gravity. With the throttle device can measure the flow, not the root device.


 


Flange level transmitter, flat flange and flange type insertion; mounting flanges No.3 and No.4, 150 No. (working pressure for the 1.89Mpa 300 No. (working pressure for the 4.95Mpa) four combinations can be for a combined for users to select. Wetted materials except 316 stainless steel, and Hastelloy, Monel and tantalum, can be used in corrosive medium.


 


The delta chamber metal seal as the sensing element, the problems of poor resistance to impact and vibration in the transmitter to eliminate the mechanical way to transmit force; eliminate the error of the external force and torque caused by to ensure transmitter has high stability, and reduce the static pressure (13.79Mpa to 31.0Mpa) caused error; due to the use of delta room roughly the same shape and size of each variety, 1151 throughout the series from pressure measuring 0.12mpa micro differential pressure type to measure 41.37Mpa has roughly the same shape and weight.

1151 type transmitter design is exquisite, has the explosion-proof and all-weather structure. Installation, use and adjustment are convenient and simple. The terminal and the amplifying circuit are placed in the upper closed electrical chamber and separated from each other. So when the connection, the amplifier is still under the condition of sealing work. The amplifying circuit has the reverse polarity protection, prevents the transmitter from the wrong and the wrong. 1151 the volume change of the working time is less than 0.16 ml, it can prevent the change of the medium liquid column, so it can not increase the amount of the compensation and the condenser or liquid level tube. The tantalum, Hastelloy alloy (Hastelloy) and Monel, Monel alloy, corrosion resistant material, in order to adapt it to the measurement of the corrosion medium. The integrated circuit elements and plug type printed circuit board, the fault less, convenient maintenance, reducing the spare parts, reduced maintenance costs.


 


Working principle


 


Measured media pressure by delta room isolation diaphragm (LT and DP/GP 1199, the remote transmitter is measured pressure after a diaphragm and filled with silicone oil or fluoride oil sealed capillary system then is passed to the delta of the isolation diaphragm) and the filling oil filled passed to the measurement of center diaphragm. In addition to AP absolute pressure transmitter, on the other side of the measurement of diaphragm is absolute vacuum reference point, other varieties of measurement of diaphragm on the other side of not atmospheric pressure is measured differential pressure of the low-pressure side. Measurement of diaphragm is a pre tight elastic element, the displacement and measured media pressure is proportional to, the maximum displacement is only 0.10 mm, measurement of diaphragm position by it on both sides of the capacitor fixing plate detection. The differential capacitance of the measuring diaphragm and the two capacitance fixed plate is linearly converted to the second line current signal of 4 ~ 20mADC.
