Full-Bridge Strain Gauges for Force Transducers

BCM SENSOR full-bridge strain gauges are specially developed for manufacturing precision force transducers which employ bending

beam working principle. For the purpose of this specific application, the full-bridge strain gauges are temperature and creep

compensated, and they can be either encapsulated or open-face according to the requirement.

The karma gauges can be manufactured with effective modulus compensation (EMC). The EMC gauges are mostly for manufacturing

low-cost force transducers, because with the EMC gauges the manufacturers can eliminate the use of compensation resistors and

achieve the sensitivity compensation.

For creep compensation, there are 18 creep codes: “N10, N9, N8, ..., O, ..., P5, P6, P7". The “N10” is the most negative creep code,

while the “P7" is the most positive one. The “O” stands for a moderate creep code. For a specific strain gauge, please find its available

creep code(s) at the column “&” in its selection chart. For a customized creep code, consult BCM SENSOR.

For more information on temperature compensation (STC), creep compensation, and EMC of strain gauges, please refer to the

corresponding articles respectively on the website of BCM SENSOR.

Ordering Information

Notes: (1) This code is only applicable to either the half- or full-bridge SG.

(4) Working temperature ranges of the wires:

EW: -40 ~ +150°C; PW: -40 ~ +105°C; HW: -80 ~ +250°C.

(2) It is recommended to select this option, if one wants to use the karma gauges and has no any experience having soldered

leads or wires onto the karma gauges.

(3) 30mm is a standard length. The customized length is available on request.

Notes:

(*): The tolerance and dispersion of the gauge resistance is influenced by both the level of resistance and the gauge pattern. The

specific tolerance and dispersion can be found in for the specific gauge pattern of metal foil strain gauges (SG).

(***): The available creep codes can be found in Selection Chart for the specific gauge pattern of metal foil SG.

( ): The maximum working current of SG is determined by the heat dissipation of SG. The heat dissipation of SG depends on the

quality of bonding process (gluing and curing), the quality of sensor body material, and profile of the sensor body. For a given SG

resistance, the maximum excitation voltage of sensors is determined by the maximum working current of the SG. If there is a

sufficient heat dissipation channel underneath the SG, the maximum excitation voltage may be set to 12Vdc crossing the

Wheatstone bridge circuit of the SG of 350Ω resistance, to keep the working temperature of the Wheatstone bridge circuit within

the compensated temperature range of the sensor. Nevertheless, if the heat dissipation channel is not sufficient to dissipate the

heat, due to the limit of dimension or profile of sensor body, the heat which is created by the working current may cause a localized

increase of temperature in the Wheatstone bridge circuit. To keep the working temperature of the Wheatstone bridge circuit within

the compensated temperature range of the sensor, it is recommended to lower the maximum excitation voltage e.g., not higher

than 10Vdc crossing the Wheatstone bridge circuit of the SG of 350Ω resistance.

Selection Chart

(**): The fatigue life of metal foil SG was tested by tensile strain. The number of cycles of fatigue life of metal foil SG was tested and

obtained when the tensile strain level was set at 1000με. The lower the tested strain level, the more cycles or longer fatigue life of

the metal foil SG under test. When the tested strain level is lower than 200µɛ, the metal foil SG under test may have much longer

fatigue life.
