1151AP absolute pressure transmitter
I. Introduction
1151 transmitter has a very rich varieties, which can accurately measure differential pressure Tai differential pressure, low pressure to high pressure, liquid level, vacuum and gravity. With the throttling device can also measure the flow, do not use prescription device. Flange type level transmitter with flat flange and insert flange; mounting flange has 3 # and 4 #, 150 # (working pressure is 1.89Mpa) and 300 # (working pressure is 4.95Mpa) four kinds combinations are available for users to choose the combination. 316 wetted materials other than stainless steel, as well as Hastelloy, Monel and tantalum, can be used in corrosive media.
Δ metal sealed chamber as the sensing element, the transmitter shock and vibration to eliminate the problem of poor mechanical way to transmit force; eliminate errors caused by external stress and torque, ensure the transmitter has a high stable performance, while reduced static pressure (13.79Mpa ~ 31.0Mpa) errors caused; the use of all varieties of roughly the same dimensions δ room, so the whole series from 1151 measuring differential pressure type 0.12Mpa to measure 41.37Mpa pressure type, are It has substantially the same shape and weight.
1151 transmitter compact design, explosion-proof and weather structures. Installation, use and adjustment are very convenient and simple. Terminals and amplifier circuit disposed at an upper portion of the electrical sealable chamber and spaced apart from each other. So the scene wiring, the amplifier still sealed state work. Amplifier circuit reverse polarity protection to prevent damage due to the wrong and transmitter. The amount of change in 1151 when the volume of work of less than 0.16 ml to prevent excessive changes in the measured medium of the liquid column, thus no need to compensate for changes in the volume of the amount or level by setting the condenser tube. Tantalum, Hastelloy (Hastelloy) and Monel (Monel) alloy corrosion resistance material, in order to adapt the measurement of corrosive media. Integrated circuit components and plug-in type printed circuit board, so that less failure, easy maintenance, reduced spare parts, reducing maintenance costs.
working principle
Measured media pressure by δ chamber diaphragm (LT and with 1199 DP / GP remote transmitter is a measured pressure to go through a diaphragm and filled with silicone oil or fluorine oil sealed capillary system again measuring diaphragm is transmitted to the diaphragm chamber δ) and which reached the center of the oil-filled irrigation. In addition to the AP-type absolute pressure transmitter, and the other side of the measuring diaphragm of the reference point is absolute vacuum, the measuring diaphragm of the other side of the other species is not atmospheric pressure, the low pressure side of the differential pressure is measured. Measuring the elastic element is a pre-tensioned membrane, the pressure is proportional to the displacement and measured medium, the maximum displacement of only 0.10mm, measuring the capacitance between the fixed plate diaphragm position detected by its sides. Two capacitance measuring diaphragm and fixed plate differential amplifier circuit capacitance is linearly converted into 4 ~ 20mADC the wire current signal.
