GAOPIN NGP5-VOC-A fixed VOC alarm, range: 0-200ppm

NGP5-VOC-A

Fixed VOC alarm instrument

Overview

Gaopin Technology NGP5-VOC-A fixed VOC alarm is an online VOC Gas Detector, which is used for 24-hour continuous online monitoring of gas concentration on site, 1.7-inch high-definition color screen display on-site concentration, on-site sound and light alarm (optional), remote signal transmission. The gas sensor of the international good brand is adopted, and the detection principle is the principle of thermal conductivity. NGP5 series Gas Detector is suitable for detecting the concentration of gas in pipelines or confined spaces and atmospheric environments, gas leakage and high concentration of nitrogen or oxygen in various background gases. More than 500 types of tests have been tested. The rugged explosion-proof shell is suitable for all kinds of dangerous places and harsh industrial environments, and is widely used in petroleum, chemical, metallurgy, refining, gas transmission and distribution, biochemical and other industries.

Features

● Free switching of units

● Diversified communication methods

Real-time monitoring can be carried out through wired or wireless remote transmission and network transmission, three-wire 4~20mA standard signal and standard bus RS485 (modbus-RTU) output at the same time, optional frequency output 200-1000Hz, Hart protocol signal, 1~5V output, two-wire system 4~20mA, SMS alarm, wireless transmission (2~5 km or unlimited distance), compatible with secondary instruments, data acquisition module, PLC, DCS system, can drive related equipment.

● Infrared remote control

The infrared remote control is equipped as standard, and the function keys of the infrared remote control can be operated with one button, which can realize the operation without opening the cover in dangerous situations, such as: modify the alarm point, concentration calibration, zero point calibration, silence, factory recovery and other functions.

● Rich man-machine interface

1.7-inch high-definition color screen, showing real-time concentration and alarm status.

● High Temperature Gas Detection (Optional)

The optional high-temperature and high-humidity pretreatment system can detect high-temperature flue gas.

● Data recovery function, in case of misoperation, you can choose to partially or fully recover.

● You can set whether to display the maximum and minimum values.

● A variety of alarm methods, multi-directional three-dimensional indication of alarm status when alarming.

Including: 2 sets of relay switching output, sound and light alarm (optional), display visual alarm. The types of alarms include: concentration alarm, fault alarm.

● Multiple alarm mode settings: low alarm, high alarm, interval alarm, weighted average alarm.

●Misoperation identification function: Misoperation of concentration calibration is automatically identified and prevented to avoid defects caused by human factors.

● Zero point automatic tracking, long-term use is not affected by zero point drift.

● Multi-level calibration of the target point to ensure the linearity and accuracy of the measurement.

● Chinese or English interface can be selected.

● Operating temperature: -40~+70°C, support temperature compensation.

● Logging.

Record calibration logs, maintenance logs, fault records, fault resolution countermeasures, sensor life expiration reminders, and next concentration calibration time reminders.

● Intrinsically safe circuit design, explosion-proof, with secondary lightning protection and anti-static capabilities. It meets the national standard and resists the impact of high-intensity pulse surge current. It has the function of anti-reverse connection. EMI AND C EMC compliant.
