Crowcon has announced that its intrinsically safe TXgard-IS+ gas detector is now UL certified.

The detector is fitted with electrochemical sensors that can detect a range of toxic gases and oxygen.

Gases detected include those commonly found in industrial applications, such as carbon monoxide, hydrogen sulphide, chlorine, ammonia, nitrogen dioxide, sulphur dioxide and oxygen.

Already certified to ATEX and IECEx standards, the addition of UL certification means that the TXgard-IS+ can now be used globally, including in North America, the Middle East and Southeast Asia, in Zone 0, 1 or 2 or Division 1 or 2 hazardous areas when used with a safety barrier (zener barrier or galvanic isolator).

Typical environments where the TXgard-IS+ can be used include plastic, rubber, chemical and semiconductor manufacturing plants, water and sewage treatment plants, steel manufacturing facilities, oil-and-gas drilling and processing facilities, car parks and tunnels.

The TXgard-IS+, which is said to be tough and hardwearing, includes IP65 ingress protection and has been used in industrial and offshore oil-and-gas installations worldwide.

It features a display menu and a keypad, which simplify maintenance and provide diagnostic facilities that enable one-person, non-intrusive calibration, according to the company.

The detector offers configurable display options and configurable fault and inhibit currents.

By displaying line voltage, there is no need to access test points inside the unit.

The signal current can be ramped manually to a desired value to simplify commissioning with control panels.

Sensor signals are temperature compensated and the device is compatible with virtually any 4-20mA control system.

The TXgard-IS+ combines its power and signal in just two wires, so only one zener barrier is required.
