Product Introduction

ETCR1900 High Voltage Approach Electricity Anti-Touch Warning Alarm, also known as crane near electric alarm, crane anti-touch warning device, crane high voltage anti-touch warning device, When the work vehicle approaches the high-voltage transmission line at certain distance, the device sends an alarm signal to remind the worker that the equipment is approaching the high-voltage power, paying attention to the danger, avoiding the lifting arm of the work vehicle from touching the high-voltage transmission line, and protect the safety of the worker and power facility. The device is easy to operate and install, providing a safe, practical, and convenient high-voltage warning device for worker working in high-voltage line environment.
ETCR1900 High Voltage Approach Electricity Anti-Touch Warning Alarm is consisted of sensor, external battery, receiver, Bluetooth APP. The sensor adopt with non-contact induction technology to monitor the high-voltage electric field, receiver receive the monitoring signal sent by the sensor. When the electric field strength reach the setting alarm value, the alarm function will be triggered to emit sound and light alarm as well as voice alarm. The sensor and receiver adopt with wireless communication, with transmission distance of 200 meters. The device has alarm sensitivity adjustment and boundary alarm functions, and users can set alarm sensitivity or self set alarm distance in the receiver to adapt to complex electric field environment. The receiver has a 485 interface and Bluetooth function, making it easy to develop it again. After installing the APP on the mobile terminal, you can view alarm signal or set alarm parameter.
1.Omnibearing electricity verification function: The sensor adopt with planar antenna to detect electric field in air environment 360°all-round, without blind angle for electrical testing.
2.Electricity verification voltage range: 1kV~500kV, not request to choose voltage level for users, avoid safety hazard caused by misoperation.
3.Sensitivity selection function: The receiver has three fine-tuning levels: high, medium, and low. User can choose the alarm sensitivity. The higher the sensitivity, the farther the alarm distance, in order to meet the need of user in complex electric field environment.
4.Boundary alarm function: Boundary alarm allows user to set their own alarm distance to meet their special need in special situation when the standard set distance cannot meet their need.
5.Sound and light alarm function: When the alarm function is triggered, the receiver alarm indicator light continuously flashes, the buzzer emits "beep-beep-beep", and the speaker broadcasts a voice prompt "Electrical hazard, please do not approach".
6.Battery level reminder function: When the battery level of the sensor and receiver is lower than 6.7V, the receiver will issue a voice prompt “sensor/receiver battery is low” to remind you to replace the battery or charge it as soon as possible.
7.Wireless communication interruption reminder function: When the wireless communication between the sensor and the receiver is interrupted, the receiver sends a voice prompt “Wireless communication is interrupted” to remind the user to check the antenna to ensure the reliability of the radio alarm.
8.485 communication: The receiver is equipped with 485 interface (USB), supports MODBUS protocol, and can upload electric field strength, battery level, alarm information, and alarm parameter settings to facilitate users' secondary development.
9.Bluetooth communication: Support Android system.After installing the APP on the mobile phone, you can view the alarm signal or set the alarm sensitivity.
