The MNM Scales 2,000 lb tension/compression load cell scale is a calibrated 2,000 lb x 0.5 lb S-type force-measurement system supplied with a digital indicator, rechargeable battery, power supply and two eye bolts. It is designed for users who need a complete ready-to-use package rather than a bare analog transducer. The S-beam can measure axial tension or compression, while the indicator adds Peak Hold, gross/net weighing, accumulation, printing, counting, check weighing, Auto Hold, lb/kg selection and RS232 output.
Capacity, Resolution and Included Hardware
MNM configures this system for 2,000 lb capacity with 0.5 lb displayed increments. The package includes an alloy-steel S-type load cell, digital LED indicator with built-in rechargeable battery and power supply, and two eye bolts. The indicator enclosure includes a mounting bracket and hardware for desktop, wall or column use at an adjustable angle. Because it is calibrated before shipment, the system can be put into service much faster than buying a load cell and indicator separately and developing the calibration from scratch.
Digital Indicator Specifications
The listing specifies a six-digit display with approximately 1-inch characters and backlight, five double-function membrane keys, plastic enclosure and 6 V rechargeable battery. Functions include Zero, Gross, Net, accumulation, printing, counting, check weighing and Auto Hold, with Peak Hold highlighted for the complete 2,000 lb system. Units are selectable between lb and kg. RS232 provides a path to compatible printers, computers or other data equipment. The indicator is listed as 6000e, up to 30,000d, with 0.3 microvolt-per-division input resolution and the ability to excite up to eight 350-ohm load cells.
Why S-Type Geometry Is Versatile
An S-beam senses force in either tension or compression. Threaded connections at both ends allow it to sit inline between a fixed reaction point and the load. That makes the same system useful as a hanging scale, tension link in a controlled fixture, compression sensor in a test stand, or portable force-checking tool. The sensor works best when force follows its primary axis; bending, twisting and side load reduce measurement quality and can overstress the body or fittings.
Peak Hold and Maximum-Force Tests
Peak Hold is one of the most useful features when force changes quickly. It can retain maximum suspended load during a controlled lift, breakaway force in a pull test, maximum actuator thrust or the highest compression in a fixture. Reset Peak Hold before each test and use a repeatable loading method if results will be compared. A peak value is not the same as a stable static load, so record both when the application cares about each condition.
Applications: Detailed Guides
Hoist, hanging-load and rigging force measurement — for controlled suspended loads, shop hoists, small cranes, lifting fixtures and tension measurements within the 2,000 lb capacity.
Actuator, winch and industrial test-stand force measurement — focuses on linear actuators, small/medium winches, mechanical linkages, pull tests and manufacturing force fixtures.
Setup for Better Measurements
Choose connection hardware rated for the full force and arrange it so the S-beam can self-align. Mount the indicator outside the load path, inspect the cable before use, power the indicator and zero it without test force. Apply load smoothly and stay within 2,000 lb. If using compression, ensure the fixture cannot buckle or eject parts. If using tension, prevent shock and side loading. For repeated quality checks, use the same fixture geometry, pre-load, loading rate and zero procedure every time.
Troubleshooting
If readings drift, remove residual mechanical load and allow the system to stabilize. If a value changes when the cable moves, inspect the connector and cable. If a known load reads differently after the sensor has been overloaded or dropped, have calibration checked. If a hanging load swings, wait for it to stabilize or use the appropriate Hold behavior rather than expecting a perfectly steady live value. Recharge the battery fully if display behavior becomes unreliable on portable power, then compare operation on the supplied power supply.
Frequently Asked Questions
Can the 2,000 lb system measure tension and compression?
Yes. The S-type load cell is intended for both directions when the fixture applies axial force correctly.
Does it come calibrated?
Yes. MNM states that the system is calibrated and ready to use out of the box.
Can it connect to a PC?
The indicator provides RS232 output. PC logging requires compatible serial hardware, configuration and software.
Technical Documents
A specific indicator model number/PDF is not identified on the current MNM listing, so the specifications above are limited to the functions and electrical details published for this exact package.
