自動車用テレメーターシステム
Torque, strain and temperature measurements from driveshafts require reliable data transmission in harsh environments, where space is limited and large suspension displacements may occur. Combinations of standard systems parts provide the solution for single and multi channel applications.

➢ 船舶試験航行用
➢ 船舶トルクメーター
Using a battery to power the transmitter eliminates the 20mm transmission air-gap limit of inductive head powered systems. A transmission air-gap range of 150mm or more avoids shaft movement problems and a steel strapping transmitter attachment kit (CAK) simplifies installation.

Transmitter Types: TX31D, TX34D, TX35D (1 channel), TX31D/2, TX24D/2, TX32D/2 (2 channel)
Shaft Attachment Kit: CAK
Signal Pickup Head: IH1 Demodulator: RE3D (1 to 4 channels)
Quickly Installed System for Long Term Tests
Provided that shaft movement is limited to 10-15mm in any direction, the transmitter may be inductively powered to give continuous operation.
Transmitter Types: TX31D, TX34D, TX35D (1 channel), TX31D/2, TX24D/2, TX32D/2 (2 channel)
