Introduction
DA-752 detects gas leaks in industrial sites such as factories and gas storages facilities producing or using toxic gases generated during manufacturing processes to prevent accidents in advance. It continuously sucks and detects leaked gas in the field using a micro pump, so it can smoothly perform gas detection functions in environments where gas detectors cannot be installed or are difficult to manage. In addition, it converts digital signals back into 4-20㎃ standard current signals and outputs them to provide signals to various external devices such as PLCs, DDCs, and RECODERs. This makes it easier to build a more expanded and comprehensive gas monitoring environment
Features
Auto-Suction Type
Continuous measurement of leaked gas is possible on the site using a micro pump. And it can smoothly perform gas detection functions in environments where gas detectors cannot be installed or are difficult to manage.
Digital Process
A digital process based on a microprocessor implements various artificial intelligence (AI) functions to perform more convenient, accurate, and efficient gas detection functions.
LCD Display with Back-Light
The detection concentration is displayed in real time on the LCD display, allowing immediate & convenient concentration confirmation even in the dark environments with blacklight functions.
Isolation Circuit
The safety & stability of sensor output has been enhanced by configuring an isolation circuit directly within the circuit to effectively block electrical noise.
Various Signal-Output
It provides smooth signal supply to external devices through various output methods such as DC 4-20㎃, 2 Step-Relay Contact, RS-485, et
TFT Display
The 1.7″ color TFT display shows gas concentration in real time and is easy to read even in the dark.
