The 107-10B is no longer available.
Please see alternatives:-

• B12-10C
• C16-10

The 107-10B provides an output current or voltage which is proportional to the frequency of alternating voltage or pulse input signal. Accepts input frequency ranges from less than 0-1Hz to 0-10Khz. This instrument has many uses in applications including flowmetering and rotational measurements. Optional PC software enables range changing, e.g. to suit a turbine meter replacement, and optimisation of digital filtering to suit site conditions.

A range of instruments providing functions which control the rate of change in the output signal for a change in input signal. These units may also provide signal conversion. The time constant is adjustable by a front panel mounted dial. Times to FSD are calibrated to order and are typically available from 0-60s up to 0-120s.

Slow Up Fast Down Response Unit: the response curve is an exponential and the time to steady state output is the same for any magnitude of change of a rising input signal. However for a negative going change in input signal, the output response is virtually instant.

Rate Limiter: the response curve is linear giving a ramp with a fixed rate of change. The effect on the output is a response time proportional to the magnitude of the input signal change.

Slow up, Slow Down Response Unit: the reponse curve is similar to the 107-17 /0 but the rate of change is also controlled for negative going input signals
