SP3 Pulse Amplifier Signal Conditioner

The SP3 Signal Conditioner has been designed for applications where simple amplification of the output of an inductive coil is required. Typical applications include signal boosting where electrical interference along the signal cable run could cause spurious readings, or where long transmission lengths lead to attenuation of low-level outputs.

The unit is very lightweight and can be attached to any suitable surface with a self adhesive pad. Wiring is easily carried out to the integral terminal block.

The unit operates as a three wire system using a DC supply. The unit is not intended for use in exposed conditions. For applications where additional environmental protection is necessary, it must be provided by the user during installation.
