A liquid nitrogen detector is a type of device used to detect the presence of liquid nitrogen in a given system. It is typically used in industrial settings to help identify potential safety hazards or to monitor the performance of certain processes.
Liquid nitrogen is a colorless and odorless gas that is produced from the fractional distillation of liquid air. It is commonly used in industrial applications as a coolant, refrigerant, and cryogenic substance. Liquid nitrogen has a boiling point of -195.8 degrees Celsius, making it a very cold and potentially hazardous material.
The primary purpose of a liquid nitrogen detector is to alert personnel to the presence of liquid nitrogen in the system. It is important to be able to detect the presence of this gas in order to identify potential safety hazards and to ensure that certain processes are running optimally.
There are a number of different types of liquid nitrogen detectors available on the market. The most common type is a gas chromatograph, which is capable of detecting trace amounts of liquid nitrogen in a given system. Other detectors include mass spectrometers, ultraviolet-visible spectrometers, and optical detectors.
Liquid nitrogen detectors can be used in a wide range of industries, including the food and beverage, pharmaceutical, chemical, and petrochemical industries. They are also used in industrial safety applications, such as in the monitoring of cryogenic tanks or other types of hazardous material storage.
In conclusion, a liquid nitrogen detector is an important tool for keeping personnel safe and for ensuring that certain industrial processes are running optimally. By detecting the presence of liquid nitrogen in a system, personnel can be alerted to potential safety hazards or take steps to improve the performance of processes.
The Global Liquid nitrogen detector market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Oxford Instruments Analytical announced the global release of IncaDryCool, a line of liquid nitrogen-free Si(Li) EDS detectors for SEM installation. Unlike any other microanalysis detector, the detector satisfies this need by utilising a completely distinct cooling mechanism.
It offers numerous benefits over existing liquid nitrogen-free detectors and maintains the same excellent analytical performance as a liquid nitrogen-cooled detector even at low energies due to a ground-breaking, unique pulse tube cooling mechanism. There are no gas lines, dangerous gases, external compressors, or vibration-induced visual degradation. A steady mains electrical supply is the only prerequisite.
High-quality HgCdTe detectors cooled by liquid nitrogen are available from Infrared Associates, Inc. Each detector is tuned for a certain waveband, such as 2 m to 5 m, 2 m to 13 m, or up to 2 m to 24 m in our FTIR Series. HgCdTe detectors in the FTIR series are made to work as well as possible in Fourier Transform Infrared spectrometers.
The detectors, which have cut offs between 750 and 400 cm-1, provide the highest sensitivity.There are several different dewar designs that come with windows that are jammed shut to prevent interference.
Apart from the typical dimensions indicated in the subsequent table, personalised setups can be obtained upon solicitation. It is also possible to order custom glass and metal packaging that is made to work with cooling systems that the customer specifies.
A (small) cryogenic vessel can have the CryoLow fitted as a stand-alone device. An NTC sensor is used in the CryoLow to detect liquid nitrogen. If liquid nitrogen is detected by the CryoLow, it will sound an alarm until the liquid nitrogen level is adjusted.Liquid nitrogen is detected by the CryoLow using a Negative Temperature Coefficient (NTC) sensor. The sensor value is read using a specialised hardware circuit.
The circuit is adjusted to obtain the best detection point by calibrating it for the particular NTC.The sensor is positioned within the vessel at the lowest permissible liquid nitrogen height.An alert status LED on the front of the CryoLow indicates whether the liquid nitrogen level is below the sensor’s predetermined height.
