Amplifying this signal allows the user to use the data from the load cell in a more efficient and productive way. Reading its signal is difficult, but with an amplifier the job is made simpler, easier and more efficient. FEATURES The Type 131 Amplifier is designed to interface to a full bridge strain gauge based load cell or similar sensor. It can be calibrated to provide a 4-20mA output for a fixed load range from the sensor. The new design is now RoHS compliant to required industry standards with enhanced features including: • Bridge Resistance between 120 - 2,000ohms • 4 wire connection to Load Cell • Provides Bridge Excitation Voltage 8.0V • Bipolar Output is an optional configuration • Bandwith 20Hz at 3dB The amplifier is housed in an ABS enclosure allowing easy installation or mounting to a suitable surface with a single screw. SPECIFICATIONS The Type 131 sensor amplifier is available in 4 ranges to suit most applications PRODUCT FULL SCALE INPUT RANGE Type 131 (A) 0.25mV/V - 0.85mV/V Alternative Output Options and Custom Ranges can be provided OUTPUT TYPE AMPLIFIER Type 131 Load Cell Amplifier BRIEF SETUP SPECIFICATION TABLE SETUP VALUE Bridge Resistance (12V supply) Bridge Resistance (15V supply) Bridge Resistance (18V supply) Bridge Resistance (24V supply) 4-20mA Load impedance Supply current (Load Variable) SENSOR DIMENSIONS * To limit thermal dissipation, minimum bridge resistances are limit at higher voltages. This output also allows for Bipolar load ranges Icustom specificationl
