LM Micro Differential Pressure Transmitter
The core component of the LM micro differential pressure transmitter is a capacitive pressure sensing element. It forms a capacitor consisting of a stainless steel diaphragm and a fixed electrode, whose capacitance varies with pressure changes. The sensor sensing element, meticulously designed with the company’s special patented technology, and the unique detection circuit ensure excellent temperature performance and long-term stability.
The LM micro differential pressure transmitter can be used to measure differential pressure or gauge pressure. Its output can be 0-5V, 0-10V, or 4-20mA, and other outputs can also be customized. The MODEL 168 has an accuracy of ±1.0%FS, 0.4%FS, or 0.25%FS at room temperature. The temperature compensation range is -18~+85°C, and the humidity effect is less than ±0.05%FS/°C.
The LM micro differential pressure transmitter offers an excellent performance-to-price ratio and is widely used in fields such as HVAC, environmental pollution control, cleanroom engineering, medical instruments and equipment, oven pressurization and furnace wind pressure control, natural gas and coal gas pipeline network monitoring, underground ventilation, and power plant wind pressure monitoring.
