Additional Feature


 

The DMD4059 accepts an input from full Wheatstone strain bridge sensors, pressure transducers or load cells. It provides filtering, amplifies, and converts the millivolt input signal into the selected dc voltage or current output that is linear to the input. The 3-way 1200V isolation eliminates ground loops, common mode voltages and greatly reduces noise pick-up. Sense wire connections are available to give maximum accuracy. Input, output, excitation and zero offset are field configurable via external rotary and slide switches. Offsets of up to ±100% of span can be used to cancel sensor offsets or tare fixed loads. Features such as red and green LEDs vary in intensity to show input and output activity and an output test button helps with set-up and troubleshooting.

Rated 5 out of 5 by from Strain gage Signal Conditioner! Excellent quality and quick service.. Exactly what we needed. Great follow up by Omega.

Rated 5 out of 5 by from Great Product with Support This signal conditioner has a wide range of variable inputs and outputs. It is slim on the din rail so not much space is taken up. Made in the US. Support is readily available as opposed to other similar product manufacturers.

Rated 3 out of 5 by from Strain Signal Conditioner Seems decent. Simple instructions, and wiring diagram. Worried vibration will cause the zero drift.
Date published: 2022-09-26
Rated 2 out of 5 by from Poor mechanical design The zero and span pots are located well behind a paper thin escutcheon and are not centered behind the holes in the surface which makes them very difficult to find with a screw driver. The plastic spring mechanism for attaching to the DIN rail is very flimsy and does not hold the device securely.

On the DMD4059-DC model, I have one that reads almost the same pressure all the time when extruder is hot. When it is cool, the reading does not drop off. I have plugged new pressure transducer into it and it still does not read zero or anywhere close.

For the DMD4059 Strain Gauge to DC Signal Amplifier, is this model able to handle a switching power supply? If it's supply voltage type is DC and it's given an alternating current, what would happen?

Asked by: Corrie
Both variants of the DMD4059 will run on AC or DC. The DMD4059-DC Low power version will run on 9 to 30 VDC or 10 to 32 VAC. The Standard DMD4059 will run on 80 to 300 VDC or 80 to 265 VAC. They will not work with a switching power supply.

Data sheet says &quot;The DMD4059 accepts an input from 1 to 4 strain bridge sensors&quot; - what is this? It only has 1 output - are the sensors in parallel? Is there a diagram of how to do this? Can it provide excitation to several sensors that use other amps?

Asked by: Zerk
Thank you for your question? The unit will only power up to 4 sensors. You are correct that the unit will only take one input. Hope this was helpful.

DOes this device have noise filter? If so what is its cutoff frequency? To what EMI standard is it qualified for?

Asked by: Pass
Thank you for your inquiry, The DMD4059 provides some filtering for stabilizing the signal. For more in-depth information about the filter please contact our Technical Support department @ support@omega.com

is it true this part is discontinued?

Asked by: sustaining engineering
The DMD4059-DC (low power DC/AC version) currently has production issues causing a long delay for shipping. The DMD4059 (High Voltage DC/AC Version) does not have this issue. Lead time for DMD4059 is 1 week ARO
