WARNINGS
- WEIGH BARS ARE HEAVY USE APPROPRIATE LIFTING IP67 WATER & DUST RESISTANT
- DO NOT IMMERSE or USE HIGH PRESSURE WASHDOWN kg
- DO NOT OVERLOAD WEIGH BAR – CHECK BEFORE INSTALLATION
DO NOT WELD ON WEIGH BAR OR LOAD RECEPTOR ºC- CAUTION WEIGH BAR COULD BE HOT OR COLD TO TOUCH
Explanation of the Weighing System
The agWEIGHr weigh bars are commonly used to measure a static or restrained load directly applied to the top surface of the bar. This load is transferred through the mount to the load cell sensor. This signal from the load cell sensor is combined in each bar and then sent back via the cables to the Y junction located near the weight indicator and then again onto the weight indicator. The weight indicator reads this signal and then converts it to a weigh reading that is shown on the display for the operator.
The agWEIGHr weigh bars usually a set of 2 bars should be mounted securely underneath a load receptor, common are load platforms, race crush, box or crate and drafter devices including auto drafters. The weigh bar can also be mounted overhead whereby the load is pulled down on the top surface of the bar. The weigh bars can be used for weighing farm or industrial products like drums or lengths of steel directly onto the top surface of the bar
The weigh bars should also be mounted securely onto a foundation made of a hard level surface in a symmetrical layout. The positioning of the weigh bars should be as far as part as the mounting points on the load receptor can structurally be mounted to. Ideally there should be no tipping or uplift from mounting too far in from the approach or exit edges. The accuracy and repeatability of the device is highly dependent on a good installation. The agWEIGHr beam is extremely rigid but still requires a solid level surface to mount the weigh bars on top of. Ideally a concrete pad should be laid, however any firm level surface can be used.
The agWEIGHr bars are constructed to IP67 ingress protection and manufactured of epoxy coated steel and the load cell is sealed stainless steel so they are suitable for wet and some corrosive environments. Also consider drainage and housekeeping for the weigh bars so that they are not constantly immersed, or a build-up allowed of sediment inside or around the bar. Failure to do this will result in inaccuracy and possible damage.
We would strongly suggest that the agWEIGHr weigh bars be used with the other agWEIGHr accessories including our range of weight indicators and weighing system accessories.
Kit of Parts
Your weigh bars should have several parts to make up a suitable weighing device.
Weigh Bar Kit of Parts

-
Two 6m armoured cables with M12 Male and Female connectors
-
One MC5JM3 M12 Male / Female Y cable junction
-
AG-X320 or AG-R320 Indicator
Installation
Firstly, we would like to say thanks for purchasing a set of agWEIGHr weigh beams. If you are unsure after reading this guide on how best to install your weigh bars, please feel free to contact your supplier or our service department for technical assistance. The agWEIGHr weigh bars are relatively quick and easy to install as a simple weighing device.
Mount the Weigh Bars
- Mount the load bars and Load platform clear of obstructions such as fence posts, gates, electrical or water pipes. Choose a site that it well drained always consider the safety of the operator.
- The site must be level across each weigh bar top and between one weigh bar to the next.
- Provide a foundation if possible. A concrete foundation is recommended. Weigh bars can be mounted on a heavy ply board or other hard surface. Ideally the foundation should extend at least 600mm (2 feet) before the load platform in the direction that the animal will travel. This will reduce the amount of dirt, mud, etc., carried onto the load platform. Ideally the foundation should be level and the weigh bars should not be recessed into the foundation.
- Ensure that the weigh bars are aligned the same distance apart from each other (systemically spaced) or that the weigh bars top mounting holes are aligned with the load platform or race crush mounting positions. If these do not exist, then ensure that the weigh bars are located as close to the edge as possible.
- Ensure that the weigh bar feet sit flat on the foundation or concrete surface. It is recommended that the load bars are secured to the foundation. To secure the weigh bars, mark the locations of feet holes on the foundation. Use a drill and fasteners to suit the type of foundation. Tighten the fasteners to secure the load bars to the foundation. The weigh bar body should not twist or distort as the fasteners are tightened. If the weigh bar feet do not sit flat on the foundation or there is a rocking motion, clear any obstacle and pack or grout under the foot. Failure to secure the weigh bars to the foundation could result in inaccurate readings.
Mount the Load platform
Mount the load platform, crush race or other load receptor to the weigh bars using the top mounting holes with the supplied bolts or a suitable length bolt. Remember that you should not use an arc welder as this can damage the weighing sensors.
Connect the cables
Cable Connections
-
Cables with M12 Male and Female connectors
-
Male straight M12 connector for connection to MC5JM3 Y junction
-
Female straight M12 connector for connection to weigh bar M12
-
Connection to Y junction cable
Note: DO NOT OVER TIGHTEN the connectors. The connection has an O’ring seal, so overtightening does not provide any additional ingression protect but could damage the connector. Each connector has an alignment slot and a mating alignment lug and pin (male) and socket (female) gender connections
- Located on the handle end of each weigh bar is a M12 male connector. Using the straight female connector on the end of the 6m cable, connect the cable to the weigh bar connector by aligning the connectors and with a slight push and winding of the outer knurled part of the connector until it winds up snuggly. Do this to all weigh bar cables.
- On the other end of the 6m cable is a straight male gender M12 connector. Locate the MC5MJ2 Y junction cable fitting and there will be two female gender connections on one side and a single male gender connector on the other side. Connect the 6m weigh bar cables to the female gender connections. It does not matter which one. Ensure they connect snuggly.
- On the other side of the Y junction cable is a male gender connector. This connector is directly connected to the weight indicator.
- Where possible locate cables off the ground or in conduit or other pipes to protect against damage.
- When you have finished using the weigh bars the cables can be removed and stored away. Ensure that the exposed ends of the cables are kept dry and free from mud and dirt. Use provided caps where possible.
Care and Maintenance
- Good housekeeping will ensure a long life of your agWEIGHr weigh bars.
- Do not allow build-up of mud, dirt or rocks around the edges of the bars
- When cleaning do not use high pressure water spray into the load cell area. Air spray is a better option to clear out build up.
- When cleaning inspect cables for any damage. Replacement cables and additional cable lengths can be ordered as a spare part.
- When cleaning inspect for any damage to parts of the weigh bar. Replacement load cells can be ordered as a spare part.
- Do not weld onto the weigh bar or onto the load receptor. The load cells are a sensitive electronic device which can be easily damaged with strong electrical currents.
