Strain gauge - RS485 | DCell

The DCell is a miniature load cell digitiser / strain gauge digitiser designed to work with any strain gauge-based transducers to provide a high stability digital RS485 output.

The load cell digitiser's small size of just 20mm diameter and 5mm high allows it to fit inside the body of the majority of load cells and strain gauge sensors, conveniently mounted using a single M2 screw. Available output protocols include ASCII, MANTRABUS II, MODBUS RTU, CAN and CANOpen.

Optical strain gauge - os3100

The os3100 Optical Strain Gage is designed to make fiber handling easy and sensor installation fast and repeatable. It is based on fiber Bragg grating (FBG) technology. The os3100s stainless steel carrier holds the FBG in tension and protects the fiber during installation. Since there are no epoxies holding the fiber to the carrier,...

Optical strain gauge - os3100

The os3100 Optical Strain Gage is designed to make fiber handling easy and sensor installation fast and repeatable. It is based on fiber Bragg grating (FBG) technology. The os3100s stainless steel carrier holds the FBG in tension and protects the fiber during installation. Since there are no epoxies holding the fiber to the carrier, long term stability is ensured by design.
Two packaging options provide for either weld or epoxy attachment to a structures surface. Installation time is just a few minutes. Welded gages can be used immediately after attachment. Epoxy gages typically cure in less than 24 hours at room temperature, similar to electronic foil strain gages.
In side by side comparisons with foil strain gages, the os3100 is equally sensitive and accurate, while providing for greater strain range and 100 times more fatigue life. The os3100 strain gage is qualified for use in harsh environments and delivers the many advantages inherent to all FBG based sensors.
This sensor can be used alone or in series as a part of an FBG sensor array. Installation and cabling for such arrays is much less expensive and cumbersome than comparable electronic gage networks. Multiple optical strain gages can be arranged in close proximity at 0, 45 and 90 degrees for strain rosette measurements.

Optical strain gauge - os3150

The os3150 is a rugged strain gage based on fiber Bragg grating (FBG) technology.
Optimized for outdoor installations on steel structures, the os3150s stainless steel carrier holds the FBG in tension and protects the fiber during installation. Since there are no epoxies holding the fiber to the carrier, long term stability is ensured by design. For temperature compensation, the os3150 may be connected in series with an FBG temperature gage like the os4350. Alternately, the very rugged os3155 strain gage offers a strain measurement approach similar to the os3150, but also includes built-in temperature compensation. For some applications, combining both os3150s and os3155s is an optimal solution.

Installation is easy and requires just a few minutes. Since the gages are welded in place, they can be used immediately after attachment without waiting for adhesives to cure. Armored cables lead to and from each gage, making both installation and fiber protection fast and easy. The armored cable is compatible with connector protection fittings (see below) that protect splice-free series connections to strain, temperature, acceleration and other types of optical sensors. The entire strain gage package is typically covered with a protective material to complete installation for long term protection.

Optical strain gauge - os3155

The os3155 is a rugged strain gage with integrated temperature compensation. Both strain and temperature compensation measurements are based on fiber Bragg grating (FBG) technology.

Optical strain gauge - os3155

The os3155 is a rugged strain gage with integrated temperature compensation. Both strain and temperature compensation measurements are based on fiber Bragg grating (FBG) technology.
Optimized for outdoor installations on steel structures, the os3155s stainless steel carrier holds the FBG in tension and protects the fiber during installation. Since there are no epoxies holding the fiber to the carrier, long term stability is ensured by design.
The design is similar to the os3150 rugged strain gage but the os3155 includes a second FBG which provides active temperature compensation. The benefits of this approach include both more accurate temperature compensation (since the strain and temperature measurements are made in close proximity) and lower-cost installation (by reducing the need for additional cables, splices and handling to connect additional temperature gages).

The sensors can be installed in just a few minutes. Since the gages are welded in place, they can be used immediately after attachment without waiting for adhesives to cure. Armored cables lead to and from each gage, making both installation and fiber protection fast and easy. Optional protection fittings help prevent damage to series connections even in harsh environments. This enables fast reliable field connections to other optical strain, acceleration or temperature sensors on the same fiber. The entire strain gage package is typically covered with a protective material to complete installation for long term protection.

The os3200 has a self adhesive backing that holds the sensor body in place and protects the FBG while epoxy is injected. The epoxy encapsulates the FBG and bonds it to a structures surface.

In side by side comparisons with foil strain gages, the os3200 is equally sensitive and accurate, while providing for greater strain range and 100 times more fatigue life. The os3200 strain gage is qualified for use in mild environments and delivers the many advantages inherent to all FBG based sensors.
This sensor can be used alone or in series as a part of an FBG sensor array. Installation and cabling for such arrays is much less expensive and cumbersome than comparable electronic gage networks. Multiple optical strain gages can be arranged in close proximity at 0, 45 and 90 degrees for strain rosette measurements.

With each sensor, Micron Optics provides a Sensor Information Sheet listing the gage factor and calibration coefficients needed to convert wavelength information into engineering units.
Micron Optics ENLIGHT Sensing Software provides a utility to calculate and then record, display, and transmit data for large networks of sensors. Installation, qualification and other sensor information is available at: http://www.micronoptics.com/support_downloads/Sensors/.

Concrete strain gauge - os3600

The os3600 Embeddable Strain Sensor measures average strain over the length of the gage while providing integrated temperature compensation. It is based on fiber Bragg grating (FBG) technology. The os3600 is intended exclusively for embedding in concrete structures. Disk ends form a solid bond to surrounding concrete or grout. Universal ends allow the user to employ bolt-on, weld-on, or custom end brackets for attachment to rebar or other structures before embedding.
A rugged, Teflon and steel-shielded body, armored cables, and optional connector protection fittings make the os3600 suitable for harsh environments. Two FBGs are well protected inside the os3600 body. One FBG measures strain, and the other provides for integrated temperature compensation. Since there are no epoxies holding the fiber to the carrier, long-term stability is ensured by design.
