An analogue sensor known as a “4-20mA sensor” measures a physical quantity and produces an electrical signal with a current range of 4 to 20 milliamperes (mA), proportional to the measured amount.
The measured quantity can have a range of values, with the 4 mA signal being the lowest and the 20 mA signal representing the greatest. Because to its robustness and dependability, this current range is frequently employed in industrial control and monitoring applications since it can convey sensor data over long distances with little signal loss.
The 4-20 mA signal can be easily converted into a voltage signal for use by analog-to-digital converters (ADCs) or other digital signal processing devices and is also impervious to electrical noise. Moreover, the measuring circuit can directly supply power for the 4-20 mA signal, simplifying wiring and lowering the possibility of electrical interference.
Pressure, temperature, and flow sensors are a few types of sensors that require a 4-20 mA output. These sensors are frequently employed in industrial settings such as manufacturing, chemical processing, and others where precise measurement is essential.
Global 4-20mA sensor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
MaxBotix Inc. produces the 4-20HR-MaxSonar-WR ultrasonic 4-20mA sensor, which comes in a variety of packaging to make mounting easier. The various varieties include our 3/4″ NPS WR and WRC housing packages, 1″ NPS, 1″ BSPP, and 30mm 1.5 pipe thread housing.
For installation, the 4-20mA ultrasonic level sensor can be connected to a control device via a lengthy wire. This makes it easier to manage numerous sensors from a single control device.
The high resolution output of the 4-20mA ultrasonic range finders steps in 1.6mm intervals. The maximum range of the 4-20mA ultrasonic range finders is 5 metres, and its published accuracy for target distance is normally 1% or greater.
These sensors are protected from the elements in a tough IP67 package, which supports their claimed MTBF of 200,000+ hours. The sensor can operate in chemical conditions thanks to modifications that make it more resistant to chemicals. Power for sensors can range from 10V to 32VDC.
There is very little to no part-to-part variation thanks to the factory matched performance of the 4-20mA ultrasonic sensors from MaxBotix Inc. Due to their factory calibration and matching, 4-20mA ultrasonic sensors only require one certification in an application.
End user modification is eliminated once a sensor has been qualified. Simply write your function into the control device to use any of our 4-20 mA ultrasonic sensors. Because each sensor may be set up automatically, installation is quick and easy.
