To calibrate your XNX gas detector, you must perform the measurement process fully. To do this, you should place the sensor housing on the bottom of the cylinder. Next, apply the calibration procedure. Make sure to follow all the instructions carefully. If Span calibration fails, you should perform the measurement procedure again. TDLA technology is a good choice because it detects and measures gases at low air density.
Span failed xnx gas detector calibration
If the XNX gas detector has a ‘Span’ failure, you must first reset the Detector. The sensor should be within the correct range before the calibration can be performed. If it is not, you must replace the sensor. If you have several faulty sensors, you may need to re-calibrate the entire unit. The following steps are helpful if the ‘Span’ failed to occur.
Connect the Flow Housing accessory to the Certified Sensor and connect it to the sensor. The Flow Housing outlet should be exhaust to a safe place. Apply the target gas at a rate of between 0.7l/m and 1.0l/m. Once the Flow Housing is set to the required value, connect the sensor to the cylinder. The Flow Housing should be fitted to the ‘XNX’ sensor and the ‘Failed’ indicator.
It needs to be fully measured
A XNX gas detector needs to be fully measured for accurate readings. Its response to the gas is affected by unfavorable environmental conditions, including humidity and temperature changes. In addition, nerve toxicity from contaminants and high concentrations of gas can also negatively affect its performance. It also needs to be fully measured for accurate readings because it will respond to the gases it receives.
An XNX transmitter is compatible with Honeywell’s current line of industrial fixed gas sensors. It provides a single interface to manage a wide range of sensor technologies. This simplifies installation and costs while providing standard output signals. XNX detectors are flexible enough to be used with multiple types of gas detectors and are easy to install and maintain. A local IS HART terminal port is also available. This enables single-man operation and features local LEDs to indicate status.
Ways to perform xnx gas detector calibration
Xnx gas detector calibration is necessary to maintain your gas appliances in top working condition. It is a distinct procedure from nitrogen balance or known gas filtering, as it involves modifying the response of the detector to a known source. This is not to be confused with electrical bump tests, which are conducted to check that the sensors are responding to the right levels of the known gas. Here are some steps to perform a calibrated Xnx gas detector.
The first step is to position the sensor in an airtight manner, so that it is facing the gas cylinder and regulator. Afterward, press the button to set the calibration gas. After a few seconds, the device will sound an internal alarm. Once this is done, disconnect the sampling hose from the regulator and connect the hose to the calibrating gas cylinder. Finally, make sure that there are no leaks or other leaks in the area.
