Product Description: The 1151GP / DP transmitter with a remote transmission device can reliably measure the pressure or differential pressure, while avoiding the contact between the measured medium and the transmitter body.A 1151 transmitter with a remote transmission device shall be considered in the following cases.1. The temperature of the measured medium is high, and the transmitter needs to be far away.2. The side medium will corrode the measurement pipe or measuring elements.3. The measured medium is a high-viscosity liquid or containing suspended particles.4. The introduction of the measured medium into the transmitter will cause solidification or crystallization due to the temperature reduction.5. It is required to rinse the measurement system to prevent pollution.6. Health and safety must be maintained.Technical performance using the object corrosive or sticky liquid measurement range range 40—6.2~37.4kpa (0-635~381mmH2O) range 50—31.1~186.8kpa (0-3175 ~ 1905 0 m m H2O) range 6 0-117~690kpa (0-1.2~7kgf / cm2) range 7 0-345~2068kpa (0-3. 5~21kgf / cm2) range 8 0-1170~6890kpa (0-12~70kgf / cm2) output 4~20mADC.Power supply voltage 12~45VDC (see below) load resistance requires the circuit load resistance R not greater than (E-12) / 0.020 Operating principle: medium pressure is transmitted to the measuring diaphragm in the center of the chamber through the isolation diaphragm acts as an elastic element and deform with the differential pressure on both sides.The displacement of the diaphragm was measured, proportional to the differential pressure, with a maximum displacement of 0.lmm.Detection by the capacitance plate on both sides, the differential capacitance between the measuring diaphragm and the capacitance plate is converted into a second-line 4-20 m A d c output signal.Product characteristics: high ● accuracy.● stability.● two-wire system.● solid element, plug-in printed circuit board.The ● is small, lightweight, and strong and vibration resistant.● scale, zero point external continuous adjustable.● has positive migration up to 500% and negative migration up to 600%.The ● damping is adjustable and overpressure resistant.● no-mechanical transmission parts maintenance workload is less.● is the whole series of unified structure, with strong parts interchangeability.The diaphragm material for the ● contact medium is optional.● explosion-proof shell structure can be used structural parameters: indicator meter scale scale length is 45mm; indicator accuracy is 2.5; digital indicator meter accuracy is 0.5.Isolation type ds ⅡB T5 is installed in dangerous places; this safety type ia ⅡC T5; (see explosion-proof type 1151 transmitter manual for details) measuring range and zero external continuous adjustable; zero positive or negative migration, shall not make the set upper, lower limit and measurement range beyond the limit value.Maximum negative migration: 600% maximum positive migration for the minimum adjustment range: Use a temperature amplifier-40~8 for the 500% temperature range transmitter body
