Strain gauge signals are typically measured using a Wheatstone bridge<\/strong>. In this process, the very small change in electrical resistance of a strain gauge is converted into a measurable voltage difference. Usually, this bridge voltage is only in the range of a few millivolts and is given as a ratio to the supply voltage in mV\/V<\/strong>. <\/p>\n Strain gauges, or SGs<\/strong> for short, are used to measure mechanical strain. Depending on the sensor design, physical values such as force, weight, pressure, torque, or mechanical stress can be derived from the strain. Typical applications include force transducers, load cells, pressure sensors, test benches, machine monitoring, and mobile measurement systems. <\/p>\n Since strain gauge signals are very small, they require special measurement inputs. A standard analogue input for 0 to 10 V or 4 to 20 mA is generally not suitable for directly acquiring a strain gauge signal. Instead, strain gauge measurement modules are used, which provide a stable bridge excitation voltage, detect the small signal difference, and digitize the measured value with high resolution. <\/p>\n Modules such as the \u00b5CAN.4.sg-BOX<\/a> are designed for this task. It directly acquires data from strain gauge or resistance bridges, provides the bridge excitation, and transmits the digitized measurement values via the CAN-Bus<\/a>. <\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ _builder_version=”4.27.6″ _module_preset=”default” custom_margin=”||||false|false” custom_padding=”||20px||false|false” global_colors_info=”{}”][et_pb_row _builder_version=”4.16″ _module_preset=”default” custom_padding=”0px||0px|||” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_text module_id=”was-ist-ein-dms” _builder_version=”4.27.6″ _module_preset=”default” text_font=”|600|||||||” text_text_color=”#ef7c00″ text_font_size=”24px” header_2_font=”|600|||||||” header_2_text_color=”#ef7c00″ header_2_font_size=”24px” custom_margin=”||14px||false|false” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_2,1_2″ _builder_version=”4.16″ _module_preset=”default” custom_padding=”0px||0px|||” global_colors_info=”{}”][et_pb_column type=”1_2″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_text disabled_on=”off|off|off” _builder_version=”4.27.6″ _module_preset=”default” text_font=”|300|||||||” text_text_color=”#565655″ text_font_size=”17px” text_line_height=”1.4em” custom_margin=”||20px||false|false” custom_padding=”0px||||false|false” global_colors_info=”{}”]A strain gauge is a resistance sensor whose electrical resistance changes when it is mechanically stretched or compressed.

For this reason, a strain gauge cannot be evaluated in the same way as a conventional resistance sensor but is usually incorporated into a bridge circuit.

The bridge converts the small change in electrical resistance of the strain gauge into a differential bridge voltage. This voltage is recorded with high resolution using a special strain gauge measurement input.[\/et_pb_text][et_pb_text _builder_version=”4.27.6″ _module_preset=”default” text_font=”|600|||||||” text_text_color=”#ef7c00″ text_font_size=”24px” header_2_font=”|600|||||||” header_2_text_color=”#ef7c00″ header_2_font_size=”24px” custom_margin=”||14px||false|false” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][et_pb_text _builder_version=”4.27.6″ _module_preset=”default” text_font=”|300|||||||” text_text_color=”#565655″ text_font_size=”17px” text_line_height=”1.4em” custom_margin=”||50px|||” custom_padding=”0px||||false|false” global_colors_info=”{}”]A strain gauge produces only a very small change in resistance. The Wheatstone bridge makes this change measurable as a differential voltage and, when properly configured, improves sensitivity, stability, and temperature response.[\/et_pb_text][et_pb_text _builder_version=”4.27.6″ _module_preset=”default” text_font=”|600|||||||” text_text_color=”#ef7c00″ text_font_size=”24px” header_2_font=”|600|||||||” header_2_text_color=”#ef7c00″ header_2_font_size=”24px” custom_margin=”||14px||false|false” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][et_pb_text _builder_version=”4.27.6″ _module_preset=”default” text_font=”|300|||||||” text_text_color=”#565655″ text_font_size=”17px” text_line_height=”1.4em” custom_margin=”||50px|||” custom_padding=”0px||||false|false” global_colors_info=”{}”]A parameter of 2 mV\/V means that, at nominal load, the sensor provides an output signal of 2 mV per 1 V of excitation voltage.

Strain gauge signals are usually in the range of just a few millivolts and require a stable bridge excitation as well as high-resolution differential measurement.
