Gas Detector Calibration With the Sensepoint XNX Gas Detector Kit Sensepoint XCD and EC transmitters are two common types of gas detectors. Learn how to calibrate them with the Sensepoint gas detector calibration kit. These devices feature backlit LCD displays with icons and powerful advanced communications modules.
XNX gas detectors can also communicate with other gas detection devices through Modbus and Foundation Fieldbus protocols. In addition, they feature extensive language support, including English, Spanish, French, Russian, Chinese, and more.
Sensepoint XCD gas detectors are ideal all-in-one sensors that monitor a variety of gas hazards. They can be used both inside and outside and are most effective in areas where oxygen and combustible gases are present. They feature a local display and transmitter, and are fully configurable via a magnetic switch interface. This makes them the perfect choice for high-risk or difficult-to-reach locations. The Sensepoint XCD RFD is supplied with all necessary accessories for installation. It can be installed on a 2″ round support pole or wall. It is ideal for installations requiring steel wire armored cable or conduit.
The sensor has 3/4″ NPT and M20 entry points to connect to the junction box. Honeywell’s Sensepoint XCD RFD meets Class I Division 1 UL performance standards. Zero calibration is done to ensure the sensor is sensitive to atmospheric gas concentrations free of toxic and combustible substances. The baseline is zero for carbon monoxide, hydrogen sulphide, and oxygen. Sensors lose sensitivity over time due to normal degradation. Sensor poisoning also affects sensitivity. Performing a span calibration ensures that the target gas concentrations are within the operating range of the Sensepoint XCD gas detector. Calibration frequency should be determined by the risk level. For example, higher risks require more frequent calibrations.
The best practice for ensuring accurate readings is to test the monitor with a known concentration prior to use. Then, check the response of the gas detector daily for a predetermined period. If it is stable and shows no loss of sensitivity, you can extend the interval between calibrations. After a successful calibration, the warning counter will reset.
mV and EC transmitters
When it comes to gas detector calibration, you need to use the right type of transmitter. An EC or mV transmitter works best if your detector has an integrated EC/mV transmitter.
This type of transmitter gives you more control over the gas detector calibration process. It also allows you to simulate the gas event with the help of a simulation tool. XNX transmitters are available for most popular sensors. Once you have installed an EC/mV transmitter, it is time to calibrate your detector. You will be prompted to enter a calibration code, which is the name of the gas detected. This information will be displayed in the calibration window. In addition, you can change the gas name in the XNX Universal Transmitter. Once you’ve set up the calibration procedure, you can choose from different transmitters that work with XNX sensors. XNX universal transmitters can support other EC sensors.
The transmitter displays its output in three numeric formats, as well as alarm detection. The transmitter also supports a range of temperatures and operating humidity. These transmitters can be used to calibrate an XNX gas detector. Once you’ve installed the transmitter, you’ll need to configure the sensor and calibration parameters. EC and mV transmitters are the most common types of transmitters for XNX gas detectors. When calibrating the transmitters, you can also choose between mV and EC transmission. EC transmitters are typically more reliable, but the XNX Universal Transmitter has additional capabilities. The universal transmitter is capable of handling multiple gas detectors and EC/mV transmitters for calibration.
A mV/EC gas detector calibration is a great place to start. EC and mV transmitters provide accurate results in the same gas detection method. The XNX Universal Transmitter has four-20 mA outputs and refreshes the output at least twice a second. The signal is proportional to the concentration of the gas. One type of gas will eat up the oxygen in another, which will make the oxygen level lower than it should be.
