Model 4022, 4023 and 4024 Magnetic Speed Sensor Preamps are designed to convert low level sinusoidal signals from passive magnetic pickups into stable square wave pulses. They can be used with all magnetic VR sensors, allowing for greater pickup to target gaps and longer signal transmission distance.

Model 4026 Freq to Voltage or Freq to Current Converter accepts frequency input from any magnetic speed sensor, digital magnetic pickup or Hall effect zero speed sensors. Input and output configurations are field selectable. Input range is adjustable between 1100 Hz - 10 kHz or 75Hz to 1100 Hz. Output selection can be configured as 4-20mA converter, 10-50mA converter, 0-5 V FTV converter or 0-10 V FTV converter. ZERO and SPAN adjustments easily calibrate to almost any measurement range, with little interaction between the adjustments.

Model 4027 Frequency to Current Converter changes the frequency input from any active or passive magnetic speed sensor or Hall effect speed sensor to a proportional 4-20mA output. It has been configured to fit a compact 1/2" & 3/4" NPT "ELBY" explosion proof enclosure. The frequency range is field selectable to fit most applications. Input range is adjustable between 1100 Hz - 10 kHz or 75Hz to 1100 Hz. ZERO and SPAN adjustments easily calibrate to almost any measurement range, with little interaction between the adjustments.

Model 4028 Frequency to Voltage Converter changes the frequency input from any passive magnetic speed sensor or VR sensor and convert the signal to a proportional 0-10V or 0-5V output. It fits a 1/2" or 3/4" NPT "ELBY" explosion proof enclosure. The frequency range is field selectable to fit most applications. Input range is adjustable between 1100 Hz - 10 kHz or 75Hz to 1100 Hz. ZERO and SPAN adjustments easily calibrate to almost any measurement range, with little interaction between the adjustments.
