Kyowa KA-SA-200 KA-SA Linear Variable Differential Transformer Displacement Measuring Device
Made in Japan
Manufacturer: Kyowa Electronic Instruments Co., Ltd.
Model: KA-SA-200
KA-SA converts the mechanical displacement that was given to displacement sensor, into an electrical signal and is the device, which is taken out as electrical output corresponding to quantity of a displacement.
Features
✔No measurement reaction force
✔Drip-proof structure (Displacement sensor, equivalent to IP67)

| Output | ±10 V/±5 mm |
| Displacement Sensor Temperature Coefficient | ±100 ppm/°C |
Specifications of Displacement Sensor
| System | LVDT (Linear Variable Differential Transformer) |
|---|---|
| Structure | Drip-proof structure, with cable connected |
| Excitation | 5 kHz, 5 VAC |
| Operating Temperature | -10 to 80°C (Non-condensing) |
| Dieletric Strength Test | Coil & coil, coil & case 500 VAC 60 Hz 1 min |

Specifications of Signal Conditioner
| Excitation | 5 kHz, 5 VAC |
|---|---|
| Excitation Signal Switch | By using “OSC” switch, user is able to select whether to use excitation signal from inside or outside. “EXT”: Outside signal is used. “INT”: Inside signal is used. |
| Linearity | ±0.5％ or less/ 0 to Full stroke |
| Response | 0 to 200 Hz (±3 dB) |
| Zero Adjustable Range | ±10% (E.G.) KA-100/ SA-DM-K100: ±10 mm (±10%/ 0 to 100 mm) |
| Span Adjustable Range | ±20% (E.G.) KA-100/ SA-DM-K100: ±20%/ 0 to 100 mm |
| Span Adjustment Switch | By using “SPAN” switch, user is able to select whether to use the condition when it was shipped or the condition which user has adjusted. “VAL”: User is able to adjust the condition by “SPAN” (Initial condition is adjusted as same as “CAL”). “CAL”: It is fixed with the condition when it was shipped from factory. |
| Measuring Cable | Only the 5 m cable directly connected to the sensor is used between the displacement sensor and the signal conditioner for adjustment and verification. |
| Stroke Polarity | When the core rod moves in the direction opposite to the cable, output will increase. |
