Notice
• Operating voltage is DC24V (12V~ 30V) to ensure that the power supply is within the allowable range;
• Working Ambient Temperature -20~ 50 ℃, avoid using beyond the range;
• Environmental humidity is 10-95% RH (no condensation) to prevent condensation from affecting the equipment;
• Sensor life is 2~ 3 years (depending on the environment used), regular inspection and replacement;
• When the connection cable distance exceeds 1000 meters, the single wire diameter is ≥ 1.5mm, and the Shielding layer needs to be connected to the earth;
• The explosion-proof form is Probe Transmitter and Sensor are flameproof to ensure safe use in dangerous environments;
• Optional 220V to 24V Power Adapter to ensure power compatibility;
• When using computer monitoring accessories, install free host computer software and connect the conversion cable correctly.
