ACUITY IMAGING INC 070-200000 Input logic module
The load cell is supplied with a 0.5 A, 330 Hz alternating current. The secondary signal is calibrated for the correct sensitivity with a voltage divider R1 - R2 , and temperature compensation is provided by thermistors T. All resistances on the secondary side are relatively low. The output impedance is typically 1-3 Ω , which helps to suppress interference.
The equipment is a precision instrument which
although intended for severe operating conditions, must be handled with care. The load cells should not be unpacked until it is time for installation. To achieve the specified accuracy, the best possible reliability and long-term stability, the load cells must be installed in accordance with the instructions below. See also 6.4 Fault Tracing in the Mechanical Installation. • When a load cell type PFTL 101AER or PFTL 101BER is used for an acid resistant application it is recommended to use adapter plates and screws of austenitic, acid resistant steel. Information For all types of installations of these load cell types, austenitic steel must be used, preferably acid resistant or stainless steel.
