Product overview
PCM260 liquid level transmitter uses high-performance diffusion silicon piezoresistive pressure sensor as measuring element to accurately measure the hydrostatic pressure proportional to the liquid level depth, and converts it into standard (current or voltage) signal output through signal conditioning circuit, and establishes the linear corresponding relationship between output signal and liquid depth to realize the measurement of liquid depth. The product has high precision and small volume, and can be directly put into the liquid to measure the liquid height from the end of the transmitter to the liquid level, which is convenient to use. It is suitable for liquid level measurement and control in petroleum, chemical industry, power plant, urban water supply and hydrological exploration fields.
After long-term aging and stability screening, the product performance is stable and reliable, and can be applied to the outdoor site with harsh environment. At the same time, it can display the liquid level on site, zero point, and full range migration.
