The Sensor Family Behind the Codes
Liquid level sensor codes typically consist of letters and numbers. For example, in LY-100, LY represents "liquid level," and 100 indicates the measurement range. Common prefixes include:
UQ: Ultrasonic principle
RD: Radar detection type
CP: Capacitive probe
FG: Float-type mechanical sensor
These codes are like the sensor's ID card; the first two letters reveal the working principle, and the numbers display key parameters.
Hidden Features in Special Codes
Some codes indicate special functions:
Suffix "T": High-temperature resistant version (up to 150℃).
Suffix "H": Sanitary design (suitable for food and pharmaceutical applications).
Slash followed by numbers: Interface thread specification (e.g., /G1/2).
Ending with "EX": Explosion-proof type (for use in hazardous areas).
Three Essential Factors for Selection
When quickly filtering by code, pay attention to:
Range Matching: Does the code number cover actual requirements?
Media Compatibility: Contact component material (plastic/metal).
Output Signal: 4-20mA/RS485 and other communication methods.
