Portable flammable gas detector GOFL
The GOFL detector is an instrument designed to detect the leakage of flammable gases into the air in a normal environment. Its main features advantages are easy operation, simple use, small size and good mechanical resistance. The instrument allows the setting of a concentration level, the exceeding of which is indicated by an uninterrupted beeping sound.
A catalytic sensor is used as the detection sensor, which responds to a wide range of combustible gases. The instrument is calibrated to methane as standard and, due to the known sensitivity of the sensor to other gases, allows switching between a methane value or a converted propane value. The instrument is equipped with a backlighted display which shows the current concentration value of the gas being detected. The value is displayed in units of \%LFL (percent lower flammable limit) and in units of ppm. The battery status is also indicated.
A battery is hardwired into the GOFL detector to power the instrument. Recharging of the internal battery can be done using a standard adapter with a USB-C connector.
Web Sensor - two channel remote 0-20mA inputs to ethernet
Converter Web Sensor P2520 is designed for the connection of two sensors with current output into the Ethernet network. The measured
current (0-20mA or 4-20mA) can be converted to the physical quantity that is measured by the connected sensor. The converter is galvanically isolated from the Ethernet communication lines, current inputs and power supply are not galvanically isolated.
