Prior to each day’s use, every gas detection monitor should be bump tested to confirm the response of all sensors and activation of all alarms by exposing the monitor to a concentration of target gas that exceeds the low alarm set point. A bump test is also recommended if the monitor has been subjected to physical performance is in doubt. To ensure greatest accuracy and safety, only bump ...

A sensor that cannot be calibrated or is found to be out of tolerance must be replaced immediately. An instrument equipped with a toxic gas sensor that fails calibration may not be used until testing with known concentration test gas determines that accuracy has been restored, and the instrument is once again fit for use. Instruments equipped ...

5 – Replace Gas Valve This indicates a sensor failure and the gas control valve must be replaced. 7 – Replace Gas Valve Overall failure of the gas valve and will usually require replacement. If you get this code and have lukewarm water and the pilot is still on, try turning up the temperature. This has happened to us twice and both times ...
the remote sensor must be securely mounted in a fixed position. The Remote Sensor kit is not intended to be used as a hand-held sensor. • Enclosures of remotely mounted sensors contain aluminum. Be careful to avoid ignition hazards due to impact or friction when installed in Zone 1 locations.
Honeywell Analytics gas sensor technologies. XNX Universal Transmitter XNX is an extremely flexible transmitter that can be configured to accept an input from any of the Honeywell Analytics range of gas sensor technologies. It can also be configured to provide a wide variety of industry standard output signals. This enables users to have a single type of interface to all their gas detection ...
the sensor and the gas. When there is no heat transfer, the measurement system is in thermal equilibrium and the sensor is as close to the gas temperature as it will get. In reality, the sensor temperature will never be the same as the gas temperature due mainly to conduction errors. Figure 1. Typical sensor installation including thermowell and

Replace the supply and return sensor C Y 241 The return sensor contact is interrupted 6 A 227 No ionization after four startup attempts Contact the gas utility company to ensure that no nitrogen remains in the gas tank or gas supply pipes. Bleed the gas supply pipe. Replace the hot surface ignitor. Adjust the gas/air ratio. Fit the correct gas orifice. Clean and/or replace the corresponding ...
· Directly related to the issue of noise is the challenge of gas void fractions or dual-phase flow. Dual-phase flow is a condition that occurs when there is gas (or voids) entrained in liquid flows or when there is liquid dispersed within a gas flow. Initially, Coriolis sensors were susceptible to errors when flowing a dense liquid, such as water, entrained with slugs of lightweight air. When ...
