TPH-A
Noncontact Design to Shaft, High Frequency Response, High Accuracy
TPH-A torque transducers can measure torque up to 10,000 rpm. The main feature of these transducers is high rigidity and a equipped dedicated flexible coupling. The unique design with no contact parts such as slip rings, ensures safe use even for long-term measurement of an object rotating at high speeds. In addition, a built-in amplifier outputs voltage and current signals simultaneously and directly to recorder or indicator and A-D converter helps data acquisition by personal computer. TPH-A torque transducers can simultaneously measure torque and revolution speed. (Patented)
?? High torsional stiffness.
?? Noncontact design without slip rings or bearing enables
easy maintenance and accurate measurement in high speed.
?? No temperature rise due to rolling friction, ensuring stable performance.
?? No interference to signal transmission and few noises
by rotary transformer power supply method and optical signal transmission method.
?? Diaphragm-type flexible coupling provided standard.
?? Dedicated built-in amplifier gives voltage (??10V), current (12??8mA) output.
?? Tachometer output (open collector output) enables measurement
on a digital revolution counter (1 pulse/revolution).

To Ensure Safe Usage
TPH-A series torque transducers are not cased, and thus, the rotating part and couplings are exposed. Considering fatigue failures of these parts, the user should consider installation of a safety steel cover, etc.
Specially designed diaphragm couplings are incorporated into all transducers. The instruction manual describes the maximum safe misalignment from the shaft. For stable torque measurement, set the couplings to minimize misalignment.
Power cable, 2 m long
Dedicated bolt and nut (42 sets including 2 spare sets)Flange is not included. Prepare it separately.
