NET NDIR SENSORS WARMUP TIME: FULL OPERATION vs. FULL SPECIFICATIONS The Data Sheet and User Manual for all our NIDR sensors states that warm-up time is 60 seconds for full operation at 25 °C and at least 30 min for full specifications. We are often asked what is the difference between these two conditions. At power-up the sensor performs initial “bootstrap”...
A Pellistor, or catalytic bead sensor, monitors the presence of a combustible gas or vapor in air (or atmospheres containing oxygen) up to the Lower Flammable Limit (LFL). A Pellistor operates on the principle that when a combustible gas/air mixture is in contact with the catalyst surface, maintained at about 500°C as current is passed through it in a Platinum...
CATALYTIC BEAD SENSOR RELATIVE RESPONSES TO VARIOUS GASES Our Pellistor, or catalytic bead sensor, is employed to monitor the presence of a combustible gas or vapor in air (or atmospheres containing oxygen) up to the Lower Explosive Limit (LEL). A Pellistor operates on the principle that when a combustible gas/air mixture is in contact with the catalyst surface, maintained at about...
The Cyber Head from NET is an ATEX/IECEx certified stainless steel enclosure complete with sensor and electronic transmitter, designed to be used as a component of a fixed flammable gas detection system or as a full conformity standalone field device. The Cyber Head is available also in a non explosion-proof version made in plastic for residential, commercial and light industrial...
NET offers the most complete range of Non-Dispersive (NDIR) sensors on the market today for refrigerant gas detection: 44 common gases, plus two more currently under development. Those gases are available across 3 different platforms (IRNET PRO, IREF PRO, IREF LITE) and the available ranges vary according to the specific gas. For example, non-flammable refrigerants may be available only in...
Ammonia is a among the most common gases found in the industry. Vastly used in wastewater treatment, leather, rubber, paper, food and beverage industries, it is also making a strong comeback in cold storage applications and refrigeration systems due to its environmental friendliness. Ammonia toxicity is well known. The pungent smell of ammonia in the air is detectable at concentrations...
NET manufactures and sells a complete range of gas sensing devices on an OEM basis for industrial and commercial applications used by instrument manufacturers worldwide. NET does not manufacture complete instruments or detectors and let alone complete gas detection systems. Nonetheless, oftentimes users ask us for sensor installation guidelines in terms of number and location of sensors. This is a...
In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. Different Hydrocarbons have different number of atoms and molecular structure, but in most cases, they can be detected in a common area of the Infrared Spectrum, between 3.0 and 3.5 microns. In other words, a certain degree of cross-sensitivity exists between different hydrocarbon gases as...
NET offers a strong range of electrochemical cells for the detection of the most common toxic gases, including CO, H2S, CL2, SO2, NH3… in different safety applications. This very cost-effective technology has been used in the industry since the 1960s. Users often ask us clarification about 3 important parameters and the differences among them: cell life, storage life and...
Over the years, NET has determined cross factors allowing specific IREF PRO sensors - notably, R-125, R-134a, R-32, R-507, R-1234yf and R-1234ze sensors - to be used when detecting multiple other refrigerant gases, including some gases for which a dedicated sensor is not available yet from NET. This feature is extremely useful for user who wants to rationalize their P/Ns...
