General Information
The SP714-S2i is a meter-mounted pulse amplifier that amplifies and conditions low amplitude signals, typically
produced by the magnetic pickup coil of a Sponsler turbine flowmeter. The SP714-S2i transforms the low power input
signal from the pickup coil into square-wave output signals with enough energy to travel a greater distance and be
detected reliably by the electronic device, such as a flow computer or an electronic register.
The SP714-S2i includes an input signal sensitivity adjustment (R1) that permits the SP714-S2i to discriminate
between an input signal and noise by increasing or decreasing the input signal amplitude necessary to be processed
as a valid signal. This, in conjunction with being directly mounted onto the turbine flow meter, allows the SP714-S2i to
operate effectively in noisy environments.
The SP714-S2i also includes diagnostic tools. The diagnostic test oscillator (SW2) enables the operator to verify the
amplifiers operation without a signal source. The green LED (D1)indicates the power supply status. The red LED (D2)
indicates the signal frequency status.
In order to maintain IECEx compliance, the SP714-S2i is connected to the turbine flowmeter boss. The
turbine meter and SP714-S2i assembly is pressure tested at the factory, then shipped as an assembly.
