Pen Vibration Meter ( HTC – PVB-805 )

Description

HTC PVB‑805 Pen Vibration Meter – High‑Precision Acceleration, Velocity & Displacement Measurement

The HTC PVB‑805 is a compact, pen-style vibration meter engineered for quick and accurate diagnostics of industrial machinery, motors, pumps, and equipment. Powered by a piezoelectric sensor and suited for field and workshop use, it accurately captures acceleration, velocity, and displacement signals with a frequency coverage from 10 Hz to 10 kHz—perfect for preventive maintenance, predictive diagnostics, and quality control.

Multi‑Mode Vibration Measurement

With a robust piezoelectric accelerated sensor, the PVB‑805 measures:

• Acceleration: 0.1 to 199.9 m/s² (peak value)

• Velocity: 0.1 to 199.9 mm/s (real‑time RMS value)

• Displacement: 0.001 to 1.999 mm peak‑to‑peak

These ranges allow clear detection of bearing wear, imbalance, misalignment, and structural resonance. The instrument’s overall accuracy is specified at ±(5% + 2 digits), enabling reliable vibration data collection in industrial environments.

Flexible Probe Choices & Frequency Support

The PVB‑805 includes short and long probes—the short probe excels at high-frequency acceleration testing, while the long probe accesses difficult-to-reach points conveniently. Both probes provide reliable measurements in the frequency range of 10 Hz to 1 kHz for acceleration and velocity, while 1 kHz to 10 kHz is supported for high-frequency acceleration and 10 Hz to 500 Hz for displacement measurements.

Real-Time Display & Data Notification

This meter features a digital LCD that updates every 500 ms, showing readings across three data formats—acceleration, velocity, and displacement—in real time. The display auto‑rotates when necessary and includes LED backlighting for visibility in dim environments. A built-in data‑locking feature allows users to freeze measurements on screen for inspection or comparison.

Memory Storage & Auto Power-Off

Users can store up to 200 measurement sets internally, allowing review of historic readings directly on the meter. The PVB‑805 also includes an auto power-off function after inactivity to preserve battery life. Additional menu-driven options enable controlled shutdown timing, and long‑pressing the power button clears stored records as needed.

Compact, Portable & Field-Ready

Designed for maneuverability, the meter measures approximately 176 × 54 × 25 mm, weighs just 121 g, and is powered by two AAA batteries. It offers continuous operation for over four hours. Though small, the device is built to withstand typical industrial environments with working temperatures between 0 °C and 50 °C, storage down to –20 °C, and operational humidity up to 80% RH; safe use is specified up to 2,000 m altitude.

Designed for Industrial Monitoring

The HTC PVB‑805 is widely used in machine condition monitoring, maintenance, and fault diagnosis across manufacturing, electric power, metallurgy, automotive, and HVAC sectors. Technicians rely on its accurate acceleration and velocity measurements to detect early anomalies in bearings, shafts, motors, and other rotating components–helping reduce downtime and improve maintenance planning.
