Features of the hydrogen fluoride alarm
The hydrogen fluoride alarm is a detection instrument used to detect hydrogen fluoride gas. After reaching a certain concentration, an acousto-optic vibration alarm will be performed. Avoid some accidents. So what is the principle of hydrogen fluoride?The key component of hydrogen fluoride is hydrogen fluoride sensor, which is an electrochemical sensor. This component can sense the concentration of hydrogen fluoride and then generate a current signal. The current signal generated by the sensor will be processed into
Hydrogen fluoride is a kind of gas. It is colorless and irritating. It is a weak acid. Its aqueous solution is also toxic. It can be absorbed through the respiratory tract, skin and mucous membranes, which can cause deformities in human bones and teeth. Its chemical formula is HF. It is a binary compound composed of fluorine and hydrogen.
Features of the hydrogen fluoride alarm:
Sensor: The sensor head and the filter mesh are made of stainless steel and have good corrosion resistance. The filter has good air permeability.
High precision: The sensor uses imported sensitive components, featuring high precision, interchangeability and high reliability.
Industrial system docking: Signal output can be adjusted at any time according to user needs, in order to connect with industrial automation systems such as DCS and PLC.
Explosion-proof function: Pass the explosion-proof certification certificate and strictly follow the standard explosion-proof design.
Convenient maintenance: modular design, independent module design, independent sensor, so you can replace parts as long as you replace them.
Shell: The shell is made of cast aluminum, which has the functions of waterproof, dustproof and anti-corrosion. It reduces the failure rate and the volume is small, avoiding the malfunction caused by accidental water ingress, near dust and corrosion. Small size and easy installation
First, the presence of fluoride in ambient air is mostly metal fluoride, hydrogen fluoride, silicon tetrafluoride, in which the content of hydrogen fluoride is relatively small, and hydrochloric acid is required for absorption measurement.
The F ion is released. The ion chromatographic eluent for the determination of anions is alkaline, and direct analysis does not reflect the contamination of real fluoride.
