Many prerequisites come into play when selecting gas detection instruments, including maximum flexibility, high performance and minimal installation costs. Additionally, modern expectations extend to smart features and the ability to detect explosive, toxic or asphyxiant gases. The list of potential solutions soon becomes short. One proven and increasingly popular option is the iTrans 2 fixed gas detector from Teledyne Gas & Flame Detection.
Offering smart sensor capabilities that support an intelligent electronics platform, the iTrans 2 provides one or two points of detection from a single head for maximum flexibility, with both readings shown on the standard-issue LED display. Gas sensors are mountable directly to the transmitter, or remotely.
For the detection of explosive and toxic gas, or oxygen, the iTrans 2 accepts infrared, catalytic bead or electrochemical sensors. Specifically, in addition to the LEL (lower explosive limit) sensor range, the iTrans 2 is configurable with a 0 to 100% volume methane infrared sensor for biogas applications and CO2 infrared sensors ranging from 0.5% to 100% volume. All are pre-calibrated using smart technology to enable automatic sensor recognition and data transfer. The device displays sensor life data automatically after each calibration.
Offering cable-saving and time-saving installation, the iTrans 2 is suitable for almost any application via common configurations that include 3-wire (4-20 mA) and 4-wire (digital ModBus) models. Both allow for full use of the gas detector’s features and options and can be used with all iTrans 2 sensors.
The gas detectors offer analogue 4-20mA and digital RS-485 Modbus outputs. The HART communication protocol is optional, enabling remote communication across the 4-20mA signal for diagnostics, commissioning and calibration. A simple magnetic wand further supports ease of use by allowing full transmitter configuration and calibration without opening the explosion-proof housing.
The housing is supplied as standard in epoxy-coated aluminium, with an optional 316 stainless steel version available for corrosive environments. Operating temperature range is -40°C to +75°C. Although this robust specification is ideal for many heavy industry applications, the iTrans 2 also serves well in smaller systems and boiler rooms, for example. It is suitable for sectors that extend from oil and gas, offshore drilling, utilities, and petrochemicals, to water and wastewater treatment, and food and beverage production. Certifications include CSA, ATEX, IECEx, INMETRO, CCC and China Ex.
Notably, the microprocessor-controlled transmitters are capable of plug and play, stand-alone operation or multi-point system configuration. The monitor’s stand-alone operational ability is delivered via optional on-board relays that can activate alarms, horns or fans, and can also shut down a system without the need for return wiring to a central control panel.
With high levels of versatility and functionality, the iTrans 2 from Teledyne Gas & Flame Detection has proven itself in wide ranging applications.
