The DHT 1500 is the high-capacity version of our DHT. Use this tester for tension or compression applications. Standard pull lengths of 18” can be increased with optional extended rods to up to 72” to test long parts. It has higher resolution force and length to test with greater accuracy. In addition, this tester is upgradeable with more options like the Micro-Length Adjust with length stops or RS 232 port.
It comes standard with a two-line backlit LED display of force and length with deflection compensation for accurate readings at all times. It has a rugged cast aluminum and steel frame, precision rack and pinion drive with adjustments for wear and convenient hand operation to apply force and adjust length. It includes 2 position stop rods, standard length lock and mechanical overload stops to protect the tester from damage. This tester has a 0.437″ thru-hole standard.
What is length deflection compensation?
All force/lengh testing devices, regardless of manufacturer, have additional deflection by the load cell and tester frame which occurs as the spring is loaded. If you buy/use a tester without deflection compensation, measurements might include significant length errors.
Spring deflection, also known as spring travel or motion, is the action of a compression spring compressing (being pushed), an extension spring extending (being pulled), or a torsion spring winding (being twisted) when a load is applied or released. This is one characteristic (spring deflection) that is measured by a Larson Systems Spring Tester.
Larson Systems has BUILT-IN Length Deflection Compensation so that the user does not have to calculate and apply length corrections. Most competitors do not have length deflection compensation.
With a Larson Systems product, forget about calculating load cell and frame deflection when testing, we’ve got you covered.
Try our software for “Spring Testing Data at Your Fingertips”. With Larson System’s SDC Software, your spring testing data can be accessed, stored and manipulated as it is generated. Store specifications for different parts, load a set of parameters and clearly see which springs are out of spec using the on-screen graphical representation of the testing results. Save and print results or open the results file in Microsoft Excel. You have complete control of your testing data.
