MSC-001 'Scorpion' - Fractional Mud Pump Stroke Counter |
|
|
Part Number: MSC-00X
Highly accurate counter for mud pumps. Measures the end points and FRACTIONAL STROKES in between as an absolute 4...20mA signal.
This allows for smooth flow measurement reading especially at low frequency.
Spring loaded arm follows movement of the pushrod
4...20 mA 2 wire current loop output Zone 0 Ex ia IIC Certified

To calibrate the unit, mount counter at the beginning of the stroke movement instead of the end like a micro-switch. The pushrod will then push the arm outwards. At the outermost point set the 'HIGH' point, as the pushrod moves back, the spring mechanism brings the arm back in. At the innermost points set the 'LOW' point. You can now measure the two end points consistently, and also all points in between.

Advantages |
|
| - Detects speeds under 1 Hz | - Wireless signal can be integrated with ATEX and IECEx |
| - Detects normal fast speeds as usual | - Various outputs possible with wireless version, including |
| - Measures down to tiny fractions of a stroke | mimicking 'micro-switch' type output |
| - Measurement is absolute 4...20mA | - Mounts in same place as micro-switch type devices, |
| - Fully quadruple certified | anywhere in the box/coffin area |

| Installation: |
|
Hohner can provide a magnetic base that can easily be attached and removed from any mud-pump for quick installation for specific jobs. We use two 400lbs strong magnets with an on/off toggle to prevent the assembly from shearing off due to the stroke forces. |
