Standards
GB/T3836.1-2021、GB/T3836.31-2021、GB3836.15-2000、GB12476.1-2013、GB12358-2006、GBZ2.1-2007、GB4208-2008
Steps
1. Carry out function menu operations such as alarm value, zero adjustment, calibrate, reset, and address code modification of the detector through remote control without opening the lid;
2. Connection cable: 4~ 20mA choose three-core Shielding cable, RS485 choose four-core, when the distance exceeds 1000 meters, the single wire diameter is ≥ 1.5mm, and the Shielding layer is connected to the earth;
3. Wireless transmission: built-in LORA, Zigbee module for short-range wireless transmission, or external GPRS/4G module for remote data transmission to the cloud platform;
4. Alarm settings: Standard configuration of two-level alarm, can be set to conventional high and low alarm or interval control alarm.
Notice
• Operating voltage is DC24V (12V~ 30V), make sure the Power Adapter matches;
• Working Ambient Temperature -20~ 50 ℃, Humidity 10-95% RH (non-condensing);
• Sensor life is 2 to 3 years, depending on the Operating Environment;
• Explosion-proof form Probe Transmitter and Sensor are flameproof;
• When the connection cable distance exceeds 1000 meters, the diameter of a single wire needs to be ≥ 1.5mm, and the Shielding layer needs to be connected to the earth;
• Optional Accessories such as 220V to 24V Power Adapter, computer monitoring accessories, etc., the user pays the cost;
• Output signal can be selected from 4-20mA, RS485, voltage signal, switching signal or wireless signal, which needs to be configured according to requirements.
