They have been designed to offer optimum application flexibility along with durability enabling them to withstand challenging environments such those with vibrations and humidity. Their 4 – 20 mA analog outputs are powered through the current loop, while the 2222 option is also enabled for HART communication.
The sensor outputs can be configured for resistance thermometers and thermocouples, resistance sensors and also voltage signals and depending on requirements, a 2, 3 or 4-wire output can be selected. This ensures that they are extremely flexible across a range of systems and applications, helping users to minimize stock levels and reduce costs.
The standard interface allows for simple and direct programming at any time, at any location, without the need for an additional interface. Additional features include a multi-coloured indicator light which provides operators with clear visual indication of the status of measured values which also simplifies diagnostics and helps with trouble-shooting. Automatic cable compensation eliminates the need for complicated calculations, reduces the work involved for calibration and also ensures accurate measurements, regardless of cable length.
Both the 2212 and 2222 are prepared for direct display connection using UnitCom cables enabling easy on-site operation via the touch screen helping to eliminate conversion errors.
Their durable silicon rubber housing provides protection against humid environments while the 2 mounting screws with standard 33mm spacing and pressure springs ensures reliable sensor contact in DIN 43729 compatible heads, even in situations where there are vibrations
