August 23, 2016 - R. STAHL HMI Systems introduced the ET-438 and MT-438 Panel PCs. Based on the SHARK device platform, they have been optimised for onshore and offshore applications in the oil and gas industry. ATEX- and IECEx-certified, these HMIs are suitable for use in hazardous areas applications (Zone 1, 21 and 2, 22) such as managing and monitoring of drilling, purging, and directional drilling operations.
Both Panel PC types are available with either a standard AMD dual-core CPU or optionally with a top-of-the-range Intel Core i7 processor. Two junction boxes house multiple explosion-proof interfaces for increased flexibility and connection versatility. Secured data transfer is provided either by a second redundant Ethernet port, or an intrinsically safe Wi-Fi module. To enable VoIP video conferencing, the Panel PCs can also be configured with video camera and Bluetooth interfaces. To reduce reflections and glare in outdoor applications or other strong ambient light conditions, the devices are also available with anti-reflective coated front glass upon request.
This option ensures readability even in direct sunlight, with brightness levels of more than 1.200 cd/m2.
The Panel PCs are rugged with an enhanced shock and vibration resistance; the powder-coated aluminium enclosures are IP66-rated and seawater-proof. With optional integrated heating, they can be operated at ambient temperatures from -40 °C to +65 °C / -40 °F to +149 °F.
