TR-NC/8

Product catalog summary

Overview: The TR-NC/8 is a transmitter designed to measure relative vibration or axial displacement of a shaft. It interfaces directly with acquisition systems using a 2-wire current loop (4 ÷ 20 mA).

Technical Specifications:

Measuring Chain: Includes TR-NC/8 transmitter, ST-NC/8 sensor, and extension cable (both ordered separately).
Power Supply: 24 Vdc (18 ÷ 32 Vdc) with a current loop of 4 ÷ 20 mA.
Environmental Conditions: Sensor and extension cable operate from -55°C to 180°C, while the transmitter operates from -40°C to 80°C.
Measurement Types: Relative vibration and axial displacement.
Dynamic Field: 1.5 ÷ 10,000 Hz for vibration and 0 ÷ 500 Hz for displacement.
Linearity: ± 2% within the range of 0.5 ÷ 2.5mm at 100°C.
Insulation: ≥108 Ω between signal and container.

Configuration Options:

Measurement type, cable length, measuring range, target type, and certification type can be customized.
Available certifications include standard, ATEX, and IECEx for hazardous areas.

Components and Accessories:

Includes contacts for power supply and probe positioning, BNC socket for portable analyzer connection, and coaxial connector for sensor connection.
Optional accessories include probe adapters, junction boxes, and Zener barriers for hazardous areas.

Installation and Compatibility:

Compatible with various target materials such as AISI 4140, AISI 410, and others.
Extension cables and probes are available in different lengths and configurations, with options for armoured or non-armoured cables.

Catalog excerpts

VIBRATION AND AXIAL DISPLACEMENT TRANSMITTER The TR-NC/8 transmitter measures the relative vibration or the axial displacement of a shaft and it is able to interface directly in 2 wires technique (current loop 4 v 20 mA) to an acquisition system (PLC or DCS). The measuring chain is composed by a proximity sensor, an extension cable and a transmitter. It is supplied complete with: ■ No. 4 contacts: two for the 24 Vdc connection of the power supply and two for the check of the voltage gap for the probe positioning ■ BNC socket for the connection to a portable analyser ■ Coaxial connector for the sensor connection BALANCING MACHINES
