Description
Hohner Series 08 Absolute Encoder
The Hohner Series 08 Absolute Encoder SP08-007 is an intrinsically safe position sensor designed specifically for extreme applications in oil and gas drilling operations, such as mud flow return transmitter systems like the DLS-001. Engineered to operate safely in Zone 0, Class 1 Div 1 hazardous locations, this absolute encoder delivers reliable angular position measurement under severe environmental conditions.
Housed in heavy-duty 316 stainless steel with an IP66/IP67 rating, this unit withstands corrosive environments and mechanical stress. It features a specialized 0090 configuration with a 90-degree full-scale angular span and a direct 2-wire, 4–20 mA loop-powered output, 4 mA at 0 degrees to 20 mA at 90 degrees. The floating tether plate design eliminates shaft and bearing stress caused by thermal expansion, ensuring long-term accurate field performance.
