Emerson EPRO PR9268/301-100 Electrodynamic Sensor

The EPRO PR9268/301-100 is an electrodynamic sensor from Emerson. It measures absolute vibration in critical turbomachinery applications. The sensor comes in various cable lengths and can be supplied with or without a Harting connector.

Key specifications include:
Sensitivity: 28.5 mV/mm/s (723.9 mV/in/s) at 80 Hz/20°C/100 kOhm.
Measurement Range: ± 1,500µm (59,055 µin).
Frequency Range: 4 to 1,000 Hz (240 to 60,000 cpm).
Operating Temperature: -20 to 100°C (-4 to 180°F).
Humidity: 0 to 100% Non-Condensing.
The sensor can measure case vibration in applications such as steam, gas and hydro turbines, compressors, pumps, and fans. It offers a variety of orientations including omni-directional, vertical, and horizontal. The sensor is self-powered and operates within a temperature range of -20 to +100°C (-4 to 212°F) for certain models. It also offers protection classes IP55 and IP65. The sensor and 1M cable weigh approximately 200 grams.
