Product Introduction
The wireless transmission box is used for the acquisition and transmission of the 4-20 mA current signal. The input signal is a standard 4-20 mA current signal, the transmission box does not provide the power supply of the current type sensor, and the current type 4-20 mA sensor needs to be powered by itself.
Product Specification
Working voltage: 3.3VDC
Output: 0.5~2.5vdc voltage signal
Measuring range: 4-20mA
Accuracy: ≤1%F.S
Working temperature: -40~70°C
Protection level: IP67
Product feature and application
The analog transmission box circuit board is the same as the ultrasonic, density and pressure sensor circuit board, and its signal input part is connected with high-precision voltage dividing resistor for collecting 4-20 mA sensor signal, and the signal is conditioned and amplified for single chip acquisition.
Product details
After the 4-20 mA sensor input signal line is connected, the sensor explosion-proof box is assembled with the mounting bracket as shown in the figure. The G-type clamping frame is used to fix the sensor explosion-proof box to the appropriate position on the site, and the 4-20 mA output is directly output as needed. Connect to the signal terminal of the sensor board.The sensor installation area should avoid electromagnetic interference as much as possible, and the cavity should be sealed when the sensor is working.
Product qualification
All sensors either are EX type or are intrinsically safe. Zone barriers are installed in the Unit. Using well-known brand products at home and abroad, the sensors of mud logging unit have the advantage of technical and performance indicators. At the same time, the service life is long.
Delivery shipping and services
CNPS can ship the goods to you by Express, Air, or sea.
