Led display,High Accuracy Wireless Pressure Transmitter For Metallurgical Industry,Zigbee wireless communication

Description

Pressure transmitter is a kind of equipment which converts pressure into pneumatic signal or electric signal for control and remote transmission.

It can convert gas, liquid and other physical pressure parameters sensed by the load cell sensor into standard electrical signals (such as 4~20mADC, etc.), which can be used to supply secondary instruments such as alarm, recorder and regulator for measurement, indication and process adjustment.

The wireless pressure transmitter adopts the wireless remote transmission module added on this basis, which can form a pressure acquisition system with our intelligent wireless receiving terminal. This product is widely used in various industrial pressure measuring systems, such as oil fields, electric power, petrochemical and some occasions where wiring is inconvenient.

• Millimeter wave radar, the measurement accuracy can reach up to ±2mm, and the minimum measurement blind zone is 0.05m.
• The smaller antenna size satisfies the measurement of more working conditions.
• A variety of lens antennas, smaller launch angles, more concentrated energy, stronger echo signals, and higher reliability than other radar products under the same industrial and mining conditions.
• It has stronger penetration and can be used normally in the case of adhesion and condensation.
• The dynamic signal range is larger, and the measurement of low dielectric constant media is more stable.
• Multiple measurement modes, radar response in fast measurement mode

Introduction

KLD800 series 80G radar level gauge adopts frequency modulated continuous wave (FMCW) technology. The antenna emits a high-frequency FM radar signal, and the frequency of the radar signal increases linearly. The transmitted radar signal is received by the same antenna after being reflected by the measured medium. At the same time, the frequency difference between the transmitted signal frequency and the received signal frequency is proportional to the measured distance. The collected frequency difference signal is subjected to fast Fourier transform (FFT) to obtain the spectrum of the reflected echo, and the distance to the target to be measured is calculated based on this.
