Calibrator outputs preset number of pulses.
Press Release Summary:
Model CLF-11 can be connected to loop powered transmitter inputs. Signal outputs and measurement inputs are fully electrically isolated from each other to read output and input simultaneously. Square wave pulses can be generated with frequencies from 0.01 Hz to 10 kHz. Pulse height is adjustable between 100 mV and 24 Volts. Output can drive 34 mA to simulate signals from photo electrics, electro magnetic sensors and proximity switches.Original Press Release:

To simulate process conditions, model CLF-11 can be connected to loop powered transmitter inputs, allowing easy performance tests on system software. For transmitter calibration, model CLF-11 offers an integral 24 Vdc power supply and loop current read-out. Transmitter readings may be scaled into engineering units like psi, pascal, bar, etc. Readings in percent (%) on 4-20mA ranges can be obtained directly by pressing the "%/mA" key; this is useful when testing or adjusting alarm settings.
Signal outputs and measurement inputs are fully electrically isolated from each other to read output and input simultaneously. This feature helps to observe related signals like signal converters, flow computers and controllers. Almost any input-output mix can be selected.
Square wave pulses can be generated with frequencies from 0.01 Hz to 10 kHz. Pulse height is adjustable between 100 mV and 24 Volts. Output can drive 34 mA to simulate signals from photo electrics, electro magnetic sensors and proximity switches. With this powerful function, the user can even test electro mechanical devices such as counters and relays. Pulse generation can be either "free running" or a "counted number." A counter input with adjustable thresholds offers you a test facility for your digital sensors.
Any input can be converted into any output signal. For example, frequency can be converted into milliamps, millivolts into Volts, Volts into millivolts, etc. An input signal can also be converted into the same type of output but with different zero and span settings like 4-20 mA into 0-20 mA or low frequency into high frequency. Zero and span settings, for both input
and output are fully programmable. These features enable the user to create a signal transmitter (converter) when a regular type of transmitter is not available.
