The Explosive gas detector for the oil tanker pump chamber, the Rongde RDKR-1 model is a compact fixed gas detector, which measures the monitoring of low-limit explosive gas concentrations, oxygen volume percentage concentrations and H2S gas percentage concentrations. From the measured voltage signal form, on a scale, the signal is converted into a 4~20mA analog current signal to transmit far to the monitoring management area. Here the gas concentration is displayed on the fixed RDQJ gas content alarm system.
Application of Explosive gas detector for pump room:
- The most common application is the Fixed Hydrocarbon Explosion Gas Alarm System for RDQJ-1 pump chambers, in addition, sensors are also used for: petrochemicals, rubber, metallurgy, environment and fire protection applications.
Used for hydrocarbon gas alarm system fixed in the oil tanker pump room”
