6.0: Half-Bridge only Variant
This is a Half-Bridge optimised variant of the standard product. The excitation frequency is higher (see specification) and
the transducer input connector is wired to accept half-bridge transducers with standard connections.
6.1: Connecting the transducer
The 5-pin DIN plug is screwed into the case mounted socket. Transducers not fitted with a plug should be wired to the
plug supplied. LVDT transducers cannot be connected to this input.
6.2: Setting up the Half-Bridge Transducer
The setting up procedure is the same as LVDT transducers. See section 5. The sensitivity of half-bridge transducers is
generally lower than for LVDT types, the x2 and x4 gain position may have to be used.
