HRL Series – Anchor Load Cell

Product Description

HRL Series load cells consist of a high quality stainless steel. This compact load cell is designed specifically for heavy duty use on construction sites and include load cells with a range of 600 … 3 000 kN. Special designs are available upon request. The attached shielded cable includes a water-proof connector with cap. Versions without the connector are available as an option. Cable lengths are customizable according to the installation requirements; for further information please contact us. The data collected from the strain gauge is proportional to the applied force. The signal is transmitted to the monitoring unit for amplification.

                    [post_content] => The Magtrol Load Monitoring Unit is specially designed for strain gauge transducer applications. Specifically developed for use with Magtrol load measuring pins and load-force weight sensors, the LMU Series provides excitation current and amplifies the output signal of full-bridge strain gauges.

Load Monitoring Units are flexible and fully configurable due to DIP-switches and jumpers which allow the unit to be easily installed - no solder connections are required. The level detectors and the outputs can be dedicated either to the full-bridge input, to the voltage input, or to the sum of both. A built-in auto-diagnostic system detects any short circuits or signal line failures, thus allowing the system to be used in applications where safety is important. If a problem is detected, both relays are deactivated and the output voltage (respective current) changes to > 10 V DC and > 20 mA.

The LMU is fully compatible with European Community (CE) standards. Its IP 65 aluminum housing allows the system to be used in harsh environments. Using SMD (surface mounted device) technology, the LMU allows the maximum performance/ price ratio for strain gauge transducer monitoring.

                    [post_content] => Magtrol’s AN Series Load Monitor, Signal Conditioner & Display are used for processing and displaying measurements from signals generated by transducers (weight, load, pressure, torque, etc.) that use standard strain-gauge bridges, such as Magtrol’s Load Measuring Pins LB Series(), Miniature Load Pins MB-02 Series() or any Custom Sensors based on strain gauge technology. The AN Series devices are suited for indoor use. These provides selectable input ranges and excitation voltages to accommodate cells of various types and sensitivities.

In some configurations (signal amplification, safety,...) it will be necessary to use the AN Series conditioner with a LMU Series - Load Monitoring Unit. If a remote or larger display is required a GAD Series - Digital Display (with heights ranging from 57 to 400 mm) can be used.

AN 1500 M: Load Monitor, Signal Conditioner & Display

As a Signal Conditioner, the AN 1500 M is designed to process and display signals coming from various types of transducers (weight, load, pressure, torque, etc.) that use standard strain-gauge bridges. As a Load Monitor the AN 1500 M can also receive any signal within the ± 150 mV DC range coming from a shunt, a converter or any type of transmitter. The Load Monitor provides selectable input ranges (±15 mV, ±30 mV, ±150 mV) and excitation voltages (5 V, 10 V) to accommodate cells of various types and sensitivities. Two programming methods allow scaling of the meter to operate in the desired engineering units. The basic instrument is a soldered assembly composed of a main board, a tri-color programmable display and a power circuit. Standard features include the reading of the input variable as well as remote (HOLD), the reading and memorization of minimum/maximum values (PEAK / VALLEY), TARE and RESET function, and a full complement of programmable logic functions.

AN 2000 C: Signal Conditioner & Display

The AN 2000 C Signal Conditioner & Display is designed to process and display signals coming from various types of transducers (weight, load, pressure, torque, etc.) that use standard strain-gauge bridges. It can also receive any signal within the range ± 300 mV DC coming from a shunt, a converter or any type of transmitter. The Conditioner provides selectable input ranges (max. ±300 mV) and excitation voltages (5 V, 10 V) to accommodate cells of various types and sensitivities. Two programming methods allow scaling of the meter to operate in the desired engineering units. The basic instrument consists of a PCB assembly including the main board, the display and the power supply filter, to which the A/D conversion circuit and the input option are added. The functions of the basic instrument include the display of the input variable as well as the remote freezing of the display (HOLD), the reading of the stored minimum and maximum values (PEAK & VALLEY) and the TARE function with reset to zero.

The load cells of the ZC series have been designed for application in platform scales in the classes C1 to C3 according to OIML-RI 60 for platform sizes up to 600The load cells of the ZC series have been designed for application in platform scales in the classes C1 to C3 according to OIML-RI 60 for platform sizes up to 600 mm × 600 mm. They are made entirely of high strength low-hysteresis aluminum alloy with its outstanding measuring properties. The sensing element itself is a well-proven configuration of parallel benders. Metal-foil strain gauges transform the elastic deformation of the sensing element into a truly proportional electrical signal, which can be processed by an electronic weighing unit. The strain gauges are under a heavy-duty cover plate to protect them against climatic influences. As a standard, the load cells are equipped with a 1.5 m connection cable (different lengths or 6-wire connection are optional). In addition to the nominal loads given in the specification, intermediate load values can be delivered. It is a matter of course that these load cells, after calibration in N, can also be supplied as high-precision force transducers up to the accuracy class 0.05%. Due to their single-point configuration, these cells are largely insensitive to the off-center introduction of force. The load cells may also be supplied with an integrated amplifier (model ZC-E). Their electrical output can be chosen as either (0 to 10) V or (4 to 20) mA.

The ZS load cells are made entirely of a special stainless steel and are, therefore, also suitable as weighing plants under difficult environmental conditions. The sensor element itself is fabricated as a transverse body. A metal diaphragm, which is welded on to the deformation zone protects the sensitive strain gauges from environmental influences. As a result constant measuring characteristics are ensured. Compensation and adjustment elements, which are required for the exact setting of the guaranteed technical parameters, are positioned in a special chamber, which is also sealed. The load cell can be subjected to traction or compression force. An assembly kit, which can be ordered separately, facilitates the unproblematic and safe installation of the load cell in the weighing unit. As a standard, the load cells are supplied with a 3 m long connection cable. Of course, these load cells, calibrated in Newton (N), can also be supplied as high-precision transducers up to the accuracy class 0.05%.
