SCHPM450 4G wireless pressure sensor

1、Using silicon MEMS micro-pressure chip, fully digital calibration, temperature drift performance and stability are improved. 2、Two chip isolation methods：     • elastic silicone protection, mainly used for differential pressure measurement of non-corrosive gases of silicon and silica gel;     • 316L stainless steel isolation diaphragm protection, filled with silicone oil internally, suitable for measurement of media that does not corrode stainless steel .

♦It adopts stainless steel shell and anti-corrosion sterile stainless steel process connection to meet the sanitary level measurement requirements. ♦The maximum temperature resistance is 150℃～200℃. ♦It is easy to use, does not need to be disassembled during cleaning and high-temperature sterilization, and is easy to operate. ♦Supports 4-20mA/1-5vdc analog output and Hart, RS232, RS485 digital communication.

1.It adopts micro-power wireless communication mode, no wiring is required, installation is faster, safer and more convenient. 2.Wireless communication uses 2.4G ZigBee communication protocol, strong anti interference ability, 16 physical channels are optional, 65535 network IDs can be set, and networking ability is strong. 3.There is also a matching wireless switching device, which can convert many wireless pressure signals into MODBUS standard signals and transmit them through Ethernet or serial port. 

♦Made of high-strength, high-elasticity, corrosion-resistant stainless steel material ♦ Special structural design and strain isolation technology, long-term stability is also greatly improved. ♦The entire instrument is integrated to ensure reliability under high-intensity vibration and impact during the hammer installation process and use. ♦Thick and shallow inner hole structure effectively prevents mud clogging and facilitates maintenance.

♦Adopting OLED LCD display screen, supporting Chinese and English display ♦The use of microprocessors increases flexibility and functionality ♦One analog quantity+two switching quantity dual mode outputs ♦Support two calibration methods: debugger and button; Optional two point and three point calibration modes ♦Extremely low temperature fluctuation, suitable for use in industrial environments with temperatures ranging from -30 to 80 degrees Celsius ♦Very flexible switch point setting, automatic recognition of control direction, and automatic insertion of return difference ♦Excellent anti-interference characteristics.
