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.

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.

Strain Signal Conditioner
Seems decent. Simple instructions, and wiring diagram. Worried vibration will cause the zero drift.

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.

what are the dimensions of the DMD4059-DC?
Hi, thanks for connecting with Omega. In response to your question: Dimensions are as follows, 0.89 W x 4.62 H x 4.81" D (22.5 W x 117 H x 122 mm D), Height includes connectors. Please contact our Tech Support if you have any further questions.

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?
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 "The DMD4059 accepts an input from 1 to 4 strain bridge sensors" - 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?
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?
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

I'm trying to read the strain from a single strain gage. Can this device be used for that, or does it only work on a full bridge?
Daniel, The DMD4059 unit will work only with full bridge circuits, if you have a single strain gauge you may complete the bridge using a bridge completion module like the BCM-2-350R (assuming you have a 350 ohm strain gauge)

is it true this part is discontinued?
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

I have a DMD4059 and need the correct switch settings. I have a +/-2 mV/V bridge calibrator, 10 volt excitation. Want output of 0 VDC at -2 mV/V & 10 VDC at +2mV/V. Having trouble getting the zero/span pots to achieve this.
Thank you for your inquiry. Please contact our Pressure Team at pressure@dwyeromega.com and they will review and advise accordingly.
