NEW CO2 SENSOR RELEASE BY NET – THE BEST ACCURACY YET FOR 0-5% VOLUME DETECTION

Implementing our very own Dynamic Range Technology, and performing a double calibration, we are pleased to bring you the most accurate sensor yet for 0-5%vol CO2 detection. The sensor is calibrated to two different ranges of detection: 0-5000ppm (or 0-0.5%vol) 0-5%vol This guarantees superior performances at low ppm levels (±0.01%Vol accuracy for readings below 0.25% Vol) but as concentration increases the sensor automatically...

TCO-CHARGE SIZE DIAGRAM

Different gases are used every day in air conditioning and refrigeration systems. All have different thermodynamic, thermophysical and chemical properties, making it more or less suitable to a specific type of system. But when choosing a refrigerant, it is not all about technological aspects. Environmental and safety regulations, local standards, maintenance aspects and disposal considerations all play a role...

Why Size Matters for NDIR Gas Sensors

Why Size Matters for NDIR Gas Sensors NET manufactures a wide range of optical gas sensors for carbon dioxide, flammable gas, refrigerants and SF6. The sensors are provided with all required driver circuitry on-board to make their use as simple as possible. They are provided in primarily two differently sized housings:  either as a 20 mm diameter cylindrical device or...

NET REMORA MODULES

The Remora module is the newest addition to our NDIR range. This very cost effective device has the same features and gas list as the IREF-Lite but it is designed to be integrated directly on chillers and other refrigeration equipment instead of a gas detector. Every aspect of the hardware can be fully tailored on the customer’s criteria and application needs. KEY...

IS YOUR SENSOR FAIL-SAFE?

According to Wikipedia, fail-safe in engineering is “a design feature or practice that in the event of a specific type of failure, inherently responds in a way that will cause no or minimal harm to other equipment, the environment or to people”. In other words, a fail-safe system is designed to avoid situations where a fault which prevents the...

What is SIL

According to Wikipedia, “Safety integrity level (SIL) is defined as a relative level of risk-reduction provided by a safety function, or to specify a target level of risk reduction. In simple terms, SIL is a measurement of performance required for a safety instrumented function (SIF).” With certification requirements for industrial fire and gas detection (especially in Europe with the introduction of...
