Resistance
Features
An external bridge completion module must be used when instrumentation is not designed to measure a strain gauge directly. The BCM-2 Series employs metal-foil resistance elements bonded to a ceramic substrate. The packaging protects the resister circuitry and ensures long-term stability; in most cases, no additional protection is required, facilitating field use. The BCM-2 resistance elements are matched with each other and match the ceramic's thermal expansion coefficient, resulting in a low temperature coefficient of resistance (TCR).
Each module is marked with a circuit/wiring diagram for easy terminal identification and foam tape for easy attachment to the test-part surface or near the instrumentation site. Heavy, pre-tinned copper terminals facilitate the attachment of up to 22 AWG (0.64mm diameter) lead wires.
Completing a bridge circuit adjacent to the strain gage site creates a stable simple voltage differantial systme between the strain gage circuit and the instrumentation. Co-locating the strain gauges and BCM-2 also reduces the potetional for noise pickup in the lead wire system especially in situations where switch contacts, slip rings, or other mechanical connections are employed between the strain gages and instrumentation.

Successful connections and readings.
I was able to attach connecting wires to the terminals easily. With a soldering iron, I connected the wires. Using the circuit diagrams online, I completed the connection with a DC power supply, a meter, and the 120 ohm strain gauge. I'm getting good readings so far!

Works great! Takes the guesswork out of a wheatstone bridge

what are the power supply requirements for this module? how come there is no specification sheet or manual available for this product?
There is no power specification for the BCM-2. The is simply a bridge completion circuit for use with strain gages. The excitation voltage applied to the P+ and P- terminal depends on the maximum allowable excitation of the particular strain gage you are using with the BCM-2. This value varies with the size and resistance of the strain gages

What is the pitch between the solder pads?
Hello, I have contacted our engineering team for this information. Can you kindly email us at pressure@omega.com? I can forward you the response as soon as I hear from them. Thank you.

If one wanted to shunt calibrate one of these devices, which terminals should the shunt resistor be placed?
Thank you for your inquiry, shunt calibration is usually connected across the negative excitation and the negative output terminals
