load cell transmitter

It depends on your control system and cable distance. 4-20 mA is immune to voltage drop and noise, so it works better for runs over 10 meters. It also lets you power the transmitter via the same two wires. 0-10 V is fine for short connections to PLC analog inputs and doesn't require a special current receiver. If you're not sure, sending us a diagram of your setup helps us recommend the right option.

Most standard load cell transmitters are single-channel. If you need to sum or average signals from multiple cells, we recommend using a junction box that combines the mV outputs first, then feeds the summed signal into the transmitter. We also have multi-channel modules for more complex applications, but those are often built into a larger monitoring system. Let us know your application and we'll suggest the most cost-effective approach.

The standard housing usually rates IP65 for dust and water jets, which covers most outdoor cabinets. For direct burial or immersion, an IP68 enclosure is available on request. Keep in mind that terminal connections still need to be sealed properly. We include blanking plugs and cable glands, but it's good practice to keep the transmitter inside a secondary enclosure if it will see harsh weather continuously.

Absolutely. While off-the-shelf units cover 0-10 V or 4-20 mA with common zero/span adjustments, we frequently tailor the gain and offset for unusual load cell sensitivities or non-linear outputs. Just give us the load cell datasheet and the desired output range. This is a typical service for geotechnical instrumentation where sensors might output as low as 1 mV/V at full scale.

Most 4-20 mA loop-powered transmitters draw from the current loop itself and operate on 12-36 VDC. For 0-10 V output types, a separate 24 VDC supply (or 230 VAC with an optional PSU) is common. We label the operating voltage clearly on each unit, and we can pre-configure either option when you order.
