Notice
• Operating voltage range is DC12V~ 30V, DC24V is recommended
• Ambient Temperature -20~ 50 ℃
• Environmental humidity of 10-95% RH (non-condensing)
Sensor life is 2-3 years depending on Operating Environment
• Connecting cable selection: 4~ 20mA choose three-core Shielding cable, RS485 choose four-core cable
• When the transmission distance exceeds 1000 meters, the diameter of a single wire should be ≥ 1.5mm, and the Shielding layer needs to be connected to the earth
• Explosion-proof form is Probe Transmitter and Sensor are flameproof
• Optional 220V to 24V Power Adapter
• Measurement certificate is optional, the user pays the fee
