Descrizione del prodotto

SDJ-501 Shaft Vibration Protection Transmitter

The SDJ-501 is a single-channel speed monitoring and protection transmitter designed for rotating machinery with sliding bearings. This advanced transmitter provides real-time rotational speed measurement and protection for equipment including steam turbines, fans, compressors, motors, and pumps.

Key Applications

Ideal for rotating machinery with various sliding bearings, including steam turbines, fans, compressors, motors, pumps, and similar industrial equipment.

Output Interface Features

4-20mA output terminals (4-20mA "+" and "-")
On-site LED displays showing machine operating status (OK, alarm, interlock Danger, disconnection BREAK)
Isolated two-stage alarm relay output terminals SPDT
Vibration values displayed on-site and via PLC or DCS systems
Buffered output of original signal for status monitoring instruments
Flexible power supply options: 24VDC, 220VAC, or 110VAC

Continuous Speed Monitoring System

The SDJ-501 provides online real-time measurement of rotor speed while simultaneously outputting two levels of alarms. This enables early detection and protection of rotating machinery, extending equipment life and reducing maintenance requirements.

Installation & Setup

For units with existing eddy current probe systems, installation involves simple wiring connection and alarm point setting. The measurement point requires a groove engraved on the shaft (minimum 2.5cm deep and 7mm wide) for probe installation.

Factory Pre-Calibrated

All parameters are pre-adjusted and calibrated before leaving the factory. Typically, no further adjustments or calibrations are required after installation - simply connect the corresponding cables for immediate operation.

Adjustable Parameters

Two-stage alarm point settings
4-20mA output zero point "ZERO"
Instrument full-scale range calibration
Alarm reset ("RESET") functionality

Technical Specifications

Output Type	Active 4-20mA
Maximum Load	Up to 750Ω
Wiring Configuration	3-wire protection transmitter
Relay Type	SPDT single-pole double-throw
Maximum Relay Load	2A
Grounding Requirement	Single-point grounding system

Customization Options

The SDJ-501 protection transmitter can be customized to meet various field requirements, with different full-scale ranges available for selecting total speed values. A low-frequency option is also provided for measuring zero speed of steam turbines.

Note: For 220VAC or 110VAC power supply options, a separate DC +24V converter power supply is required for isolated power supply.
