1151DR2F22M2B2D1 micro differential pressure transmitter

I. Introduction

1151DR2F22M2B2D1 micro differential pressure 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 throttle device can also measure the flow, do not use prescription device.

Flange type level transmitter with flat flange and insert flange; mounting flange and a 3 # 4 # 150 # (working pressure 1.89Mpa) and # 300 (working pressure 4.95Mpa) four kinds combination available for users to choose the combination. 316 wetted materials other than stainless steel, and Hastelloy, Monel and tantalum, can be used in corrosive media.

Metal chamber sealed δ as a sensing element, the transmitter eliminate shock and vibration problems of poor mechanical force transmission; 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; since each species using substantially the same dimensions of δ chamber, so that the entire 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 easy and simple. Terminals and amplifier circuit disposed in the upper portion of the electrical sealable chamber and spaced apart from each other. So the scene wiring, amplifiers still sealed state work. Amplifier circuit reverse polarity protection to prevent damage due to the wrong transmitter. The amount of change in 1151 when the volume of work is less than 0.16 ml, to prevent excessive changes in the measured medium of the liquid column, thus no need to compensate for the amount of change in volume or level additions 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, reduce maintenance costs.

working principle

Measured media pressure by chamber diaphragm (LT 1199 and with the DP / GP remote transmitter is 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 Model AP 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 than the atmospheric pressure, the low pressure side of the differential pressure is measured. Measuring the elastic membrane element is a pre-tensioned, the pressure is proportional to the displacement and measured medium, the maximum displacement of only 0.10mm, measuring the capacitance between the fixed plate of the diaphragm position is detected by its sides. And two capacitance measuring diaphragm plate fixed differential capacitance is converted into a linear amplifier 4 ~ 20mADC two-wire current signal.
