Magnetic speed sensors manufacturing

Signal Conditioners - Signal Converters


4-20 mA frequency to current converters and signal conditioners for digital output

Frequency to Voltage & Frequency to Current Converters:

  • Meet the speed, proximity and counting application needs for magnetic speed sensors and RF pickups;
  • Magnetic sensors and RF pickups gain a greater range due to a stronger and more noise-free output signal;
  • Intrinsically Safe to Zone 0 magnetic sensor pulse amplifier, frequency to current converters and frequency to voltage converters;
  • Engineers gain a greater latitude in filling requirements for sensor placement and need for digital output by remotely mounting the signal conditioner away from the sensor - shielding the electronics from the sensor's harsh or high temperature environment;
  • Digital or pulse output format is easily read by computers or process controllers;
  • Most SPECTEC signal conditioners bear the CE marking.

Speed Sensor Signal Conditioners

Magnetic speed sensor signal conditioners for magnetic speed sensors and Hall effect sensors.

RF pickup signal conditioners for RF pickups used in flow meters and low drag sensor applications.

All signal conditioners come in various form factors for use in-line, in Appleton Y1, Y3, Crouse-Hinds GUAL16 or similar explosion-proof enclosures or for custom applications.

Frequency to Voltage and Frequency to Current Converters

SPECTEC's frequency to current and frequency to voltage converters for passive and active magnetic speed sensors and all digital speed sensors fit in a variety of explosion-proof elbow enclosures or can be DIN rail mounted via special adapters. These signal conditioners change the sinusoidal input to a linear current or voltage output respectively. The 4-20 mA and 10-50 mA signal converter has many applications in the flow industry. The frequency to voltage converters provide either a 0 to 5 V (TTL) or 0 to 10 V output.

Opto-Isolated Signal Conditioner

SPECTEC's digital Opto-isolated signal conditioner is for applications that need an interruption of the galvanic path between the input and output. The opto-isolation circuitry keeps noise on the input signal from passing through to the signal output.

SPECTEC has single and multiple output pulse amplifiers for improving and stabilizing weak signals from variable reluctance sensors.
