Tension Load cells are designed to indicate accurate readings by transmitting the applied tension load to an indicator. The Tension Loadcell is available in many sizes and is used in many applications.
Otherwise known as tension transducers, tension load cells are a style of transducer because they can convert sensed mechanical force into usable electrical signals for measurement in various applications which include mechanical testing, continuous system monitoring and as components of other measurement devices.
Our Tension Load Cells Feature:
Wide Tension Capacity Range
Available 365 Days Per Year / 24 Hours Per Day.

The Unico Polished Rod Load Cell is an accurate, reliable transducer for
measuring rod string force in sucker-rod pumping applications. It is the ideal choice for oil wells requiring pump-off control.
Designed for Oil Field
The load cells have been developed, field-tested, and accepted for oil-field use.
Units are waterproof and corrosion resistant for use in any kind of weather.
A fatigue life exceeding 50,000,000 cycles ensures many years of reliable operation.
Transient voltage protection safeguards the load cells from lightning and/or power line disturbances for uninterrupted operation.
Load cell performance is virtually unaffected by changes in temperature and is insensitive to off-center loads.
Load cells feature a safe overload of 200% of rated capacity. This provides a safe limit of 100,000 pounds with the 928-744 model and 60,000 pounds with the 928-758 model.
Load cells install directly on the polished rod. No welding or special brackets are required.

The NOV M/D Totco Pressure Transducer converts pressure into an analog electrical signal. Converting pressure to an electrical signal is achieved by physically deforming the strain gauges which are bonded into the diaphragm of the pressure transducer and wired into a bridge configuration. Pressure applied to the pressure transducer produces a deflection of the diaphragm which introduces strain to the gauges. The strain will produce an electrical resistance change proportional to pressure.
The 221212 Series Pressure Transducer is assembled with a union and installed into an electronic pressure transducer assembly (221145 Series). It is available in flanged, threaded, or weld on sub configurations and calibration certificates are provided.
Maximum Working Pressure: 15,000 psi
Overload: 150% of capacity without damage, 300% without burst rupture failure
Output: 4-20 mA, loop powered

The Hydril Pressure Control MSP-2000 PSI offers outstanding performance that sets the industry standard for simple, reliable blowout protection. Its design includes important features found in the GK® annular BOP, and it has been field and laboratory proven to deliver a long, dependable service life. In addition:
It has a screwed head design that ensures safe operation with no loose parts to be lost.
Latched head design is available.
There are only two moving parts, the piston and packing unit, for less maintenance and less downtime.
A field-replaceable wear plate eliminates metal-to-metal contact between the packing unit inserts and the BOP head, making repair fast and economical.
A bolted-in inner sleeve eliminates the need to stress-relieve if the inner sleeve is damaged in the field.
A telescoping actuating piston makes the MSP-2000 compact and lightweight.
