Which measuring instruments are suitable for outdoor or marine testing where main grid power is unavailable?

The handheld SPD-HD is highly optimized for such requirements. Featuring a 2-way power supply configuration (AA alkaline batteries or AC adapter), it can be effortlessly carried to remote sites. The integrated OLED display enables real-time verification of measurement values right on the spot.

Can data from a handheld instrument be exported to a PC or data logger?

Yes, it can. Despite its compact footprint, the SPD-HD can simultaneously output 16-bit analog signals (up to 100µs update rate) and CAN communication (up to 1ms update rate). Optional interfaces such as RS-485 and Ethernet are also available to support local verification and remote data logging at the same time.

What types of sensors can be connected to measure rotation or displacement?

The instrument supports diverse pulse input signals from magnetic gear speed sensors (IMG/FDP series), rotary encoders, flow meters, and photoelectric sensors. Since it provides an integrated sensor power supply output, you can connect sensors and begin measurements immediately without external power packs.

How can transmission noise be mitigated during long-distance signal routing?

We offer models equipped with Line Driver input specifications designed for superior noise immunity. This ensures stable data acquisition without signal dropouts or interference, even in challenging routing environments like heavy machinery inspections or measurements taken far from an engine room.
