Through Hole Compression Load Cell

Product Description

The 90610-TH is a high-precision through hole compression load cell specially designed for fastener and bolt force testing applications. The compression force is generated by tightening a fastener through the hollow center of the load cell.

It is a strain gauge-based sensor with full temperature compensation from 0C to 60C, ensuring stable and accurate measurement in industrial environments. The load cell features IP65 protection for the gauge area and is constructed from electroless nickel-plated tool steel (optional stainless steel 17-4 PH grade available).

With capacities ranging from 1 Tf to 300 Tf, it is suitable for applications such as bolt force measurement, material testing, press calibration, civil engineering testing, robotics, suspended load measurement, and prestressed concrete testing.

The sensor provides a standard output of 2 mV/V and operates with an excitation voltage of 10 VDC (max 15 VDC).

Frequently Asked Questions (FAQs)

1. What is a through hole load cell used for?

It is primarily used for bolt tension and fastener force measurement, where the bolt passes through the hollow center and tightening generates measurable compression force.

2. How is the 90610-TH installed?

The load cell is mounted on a flat surface. The bolt or fastener is passed through the center hole, and force is applied by tightening the nut. Washers are recommended on both ends to protect the surfaces.

3. What is the output signal of this load cell?

The standard output is 2 mV/V, suitable for strain gauge-based indicators and controllers.

4. What is the operating temperature range?

The temperature compensated range is 0C to 60C, ensuring stable readings within this range.

5. Can it be used for suspended load measurement?

Yes. It can measure suspended or hanging loads by proper mounting and load application through the central hole.

6. What overload protection does it have?

• Safe Overload: 150% of rated capacity

• Ultimate Overload: 250% of rated capacity

7. Is the load cell protected against dust and moisture?

Yes, the gage area has IP65 protection, suitable for industrial environments.
