Stellar Technology produces a wide variety of load cells for clients, ranging in purpose, capabilities, tension or compression operation and more. They provide high-level mV/V, analog and digital outputs (including RS232, RS485, and CANbus), and are constructed of fully-welded stainless steel, which allows the load cells to handle the rigors of any application.
Thru Hole Load Cells
Naturally, our thru-hole load cells were given that name for their functionality – that is, they are passive devices that allow load structures to essentially “pass through” the load cell itself. These serve a number of purposes across many industries, including harsher environments such as oil fields.
Series CTH932 – Pump Off Control Polished Rod Load Cell
These 0.25% accuracy load cells are designed specifically for the polished rod of an oilfield pump, and have transient voltage protection for lighting and/or power line surges.
Other features of the Series CTH932 include:
- Standard full-scale capacities range from 20,000 lbf. to 80,000 lbf.
- Removable sealed cover for cable replacement
- Fatigue life of 50,000,000 cycles (and 150% overload without damage)
- Shock and vibration rated during the manufacturing process
- Operating temperature of -40°F to 180°F
Optional features include special load ranges, special multipoint calibrations, customer-specific configurations and cable lengths, high-level outputs (analog and digital), and much more. In the harsh environment of an oilfield production site, the CTH932 is the perfect thru-hole load cell for optimal performance.
Series DTH920 – Thru-Hole Load Cell
Designed with a clear center hole for applications requiring a load structure to pass through the load cell, the Series DTH920 force transducer can be used to measure either tension or compression. These “donut-style” bonded foil strain gage forced sensors are compact and constructed of welded stainless steel, making them reliable products for a wide range of demanding applications.
Other features of the DTH920 include:
- 0.50% accuracy
- Low profile
- 2 mV/V
- -65°F to 250°F standard temperature
- 5-point calibration record traceable to NIST
With shock and vibration protection (along with custom capacities, special calibration, submersible configurations and much more), DTH920 load cells are perfect for applications involving clamping forces, bolt and fasteners forces, and structural analysis.
