Product Description

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

Patent Pending

IECEx

Technical Data		Connection Options
Operating temp:	- 20 ...+ 60 degrees C	Cable (available as wireless or with connector as well)
	- 4 ...+ 140 degrees F	+Loop	Red (+Current)
Certification:	ATEX, IECEx, CSA	-Loop	Black (-Current)
Weight:	6.6 lbs (3.0 kg)
Protection:	IP 66 / X7 M	Output
Material Sensor:	Stainless Steel	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.
Material Spring:	Stainless Steel
Material Arm:	Stainless Steel
Material Bracket:	Stainless Steel
Resolution:	0.18mA = 1 degree

Mounting of Pivot Arms
We provide several screw hole locations
for user to mount pivot arms to make contact
with the pushrod:
2x 12-24 imperial holes 1.5" apart
2x 1/4"-20 imperial holes 1" apart
2x M6 metric holes 20mm apart

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.
