Intelligent single crystal silicon differential pressure transmitter

Intelligent single crystal silicon differential pressure transmitter

Product Details

First, the product introduction

The intelligent single crystal silicon differential pressure transmitter is a meter that measures the pressure, differential pressure, liquid level and density of liquid, gas or steam, and then converts the measurement result into a 4-20 mA•DC standard current signal and transmits it to the control room . Then complete remote control and detection. This product is an on-site transmitter that needs to be installed directly on a pipe or other container. The microprocessor is the core of the circuit and the advanced digital isolation module technology greatly enhances the self-diagnosis, anti-interference and stability of the instrument. The built-in temperature sensor compensates the temperature of the transmitter. The measurement accuracy is improved, the drift caused by temperature is reduced, and the instrument has long-term stability and reliability. Structurally, the user can easily calibrate, set up and configure the transmitter via the HART communication protocol.

According to these characteristics, intelligent pressure / differential pressure transmitters are widely used in various detection and automation control in the production process of petroleum, chemical, electric power, metallurgy, medicine, food, shipbuilding and other industries.

Second, the pressure / differential pressure transmitter features

▲Adopt advanced monocrystalline silicon pressure, differential pressure sensor technology and packaging technology to carefully develop leading ultra-high performance pressure and differential pressure transmitters;

▲ One-way overload pressure can reach up to 25MPa ;

▲ High performance with a powerful 24 -bit ADC ;

▲The latest infrared setting, one-button clear function does not affect the electrical protection level, it is safer and faster;

▲Using microprocessor as the core and adopting advanced digital isolation technology, the instrument has higher anti-interference and stability;

▲In the upper and lower limits of the range, it can be set arbitrarily, as long as the calibration range ≥ set range;

▲ Output 4-20Ma•DC two-wire signal, in line with NAMIR NE43 specification, superimposing HART communication protocol digital signal, can choose linear or square root output;

▲ output signal limit, minimum 3.9mA , maximum 21mA ;

▲If the sensor or circuit fails, the automatic diagnosis function automatically outputs 22mA;
