PM800C Intelligent Differential pressure transmitter

The PM800C intelligent differential pressure transmitter takes all-digital circuit design as its core, subverting the performance boundaries of traditional analog circuits. Equipped with high-precision ASIC chips and advanced digital signal processing (DSP) technology, it is like implanting a "smart brain" into the device. It can not only achieve ≤±0.1%FS, including nonlinear accuracy, hysteresis, zero offset and full-scale point deviation, but also can withstand long-term offset in extreme temperature range environments from -20 ℃ to 80℃. ≤±0.1F.S. This outstanding stability ensures that the PM800C remains precise and reliable throughout long-term continuous operation, setting a new benchmark for accuracy in the industrial measurement and control field. In terms of communication and data management, PM800C also performs exceptionally well. It is equipped with dual 4-20mA outputs and HART protocol, enabling seamless integration into mainstream control systems such as DCS and PLC, and easy integration into industrial automation networks. From the differential pressure monitoring of high-pressure pipelines in the petrochemical industry to the precise liquid level control in clean workshops in the food and pharmaceutical fields; From high-temperature furnace pressure detection in the metallurgical industry to flow measurement in water conservancy projects, the PM800C intelligent differential pressure transmitter, with its highly integrated and intelligent features, provides one-stop, highly reliable pressure measurement and control solutions for various complex working conditions. Whether it is a harsh industrial site or a precise laboratory environment, PM800C can precisely adapt and become a reliable and capable assistant for engineers.

Petroleum refinery

Atmospheric and vacuum distillation tower: Use a differential pressure transmitter to measure the pressure drop between trays (to determine tray efficiency/blockage) (differential pressure application), and measure the feed flow rate through orifice plates (flow application). Reactor feed flow control (flow application). High-pressure separator liquid level measurement (explosion-proof and high-pressure required) (liquid level application). Pressure difference monitoring (clogging monitoring) of key pump outlet filters. All require explosion-proof certification.

Chemical Plant (Chlor-alkali) :

Electrolytic cell: Monitor the differential pressure between the anode and cathode chambers (to prevent membrane damage) (key differential pressure monitoring). Brine/alkali liquid storage tank liquid level (liquid level application). Chlorine/hydrogen gas transmission pipeline flow (orifice plate + differential pressure) (flow application). The process involves hydrogen and has strict explosion-proof requirements.

Thermal power plant

Boiler: Drum water level measurement (one of the most critical safety parameters, often using redundant differential pressure measurement) (liquid level application). Primary air/secondary air flow rate (duct anuba + differential pressure) (flow application). Negative pressure in the furnace (slight differential pressure, which is crucial for combustion safety) (differential pressure application). Differential pressure monitoring of air preheater (to determine ash accumulation and blockage) (blockage monitoring). Differential pressure at the inlet and outlet of the coal mill (reflecting the fineness of pulverized coal and load) (differential pressure application).

Pharmaceutical Factory (API synthesis) :

Reactor: Liquid level measurement in a closed reactor (double flange differential pressure or single flange + gas phase compensation) (liquid level application). Solvent feeding flow control (mass flowmeters are expensive, and differential pressure types are used for non-critical or large flow points) (flow applications). The reaction area involves flammable solvents such as ethanol and acetone, and explosion-proof certification is required. CIP system filter differential pressure monitoring (clogging monitoring).

Sewage treatment plant

Biological reaction tank: Differential pressure monitoring of aeration network (to determine if the aeration head is clogged or the blower is faulty) (clogging/performance monitoring). Inlet pipe flow measurement (open channel or pipe flow meter, some use differential pressure) (flow application). Sludge storage tank liquid level (liquid level application). Biogas tank pressure/liquid level (Biogas is flammable, explosion-proof is required) (pressure/liquid level application).
