HDA 4700 Electronic Pressure Transmitter ATEX, IECEx Intrinsically safe Dustproof housing Non-sparking With HART Interface

The HDA 4700 with HART interface is a compact pressure transmitter (intrinsically safe version) which is used to measure relative pressures in hydraulics and pneumatics. The double approval in accordance with ATEX and IECEx enables universal, almost worldwide utilization of the devices in potentially explosive atmospheres.

As with the industrial version of the HDA 4700, those with triple approval have a proven, fully-welded stainless steel measurement cell with thin film strain gauge without internal seals.

The main areas of application are in mining and the oil and gas industry, e.g. in underground vehicles, hydraulic power units, blow-out preventers (BOPs), drill drives or valve actuation stations as well as in areas with high levels of dust contamination.
