Pillow Block Sensors BZH

Product catalog summary

Overview
The BZH series web tension sensors are designed with a compact pillow block structure, suitable for direct measurement of web tension forces in materials such as paper, textile, plastic, film, or metal. The sensors consist of two mounting plates connected by measuring elements, compatible with pillow block bearings from manufacturers like INA, FAG, SKF, and NSK.

Specifications
The sensors operate on the double beam principle, capturing forces via strain gauges. HAEHNE provides amplifiers to condition the measuring signal and supply bridge voltage. The output signals are proportional to the horizontal force and can be displayed digitally or used in control loops.

Special Features

Compact design
Adaptable to various bearing designs and sizes
High overload protection with mechanical stops
High resonant frequency

Scope of Supply
The force sensor comes in a pillow block design with a 5 m PVC cable and connection variant T (straight cable gland).

Variants and Options

Variant S: Right-angled plug connection, MIL
Option F: Suitable for explosive areas, includes J-Box

J-Box Special Features • Compact design • Easy modification to different bearing designs and sizes • High overload protection utilizing mechanical stops • High resonant frequency Wire assignment V4: Supply voltage V1: Signal voltage Odering example BZH15R160-TF Type Size Design Nominal force Variants/ Options The web tension sensors BZH series are characterized by a compact pillow block design. They are suitable for a variety of applications, especially for the direct measurement of web tension forces, e.g. in moving webs of paper, textile, plastic, film, or metal. The sensors basically consist of two mounting plates which are connected by measuring elements. The mounting plates are designed to accommodate pillow block bearings of the following manufactures: INA, FAG, SKF and NSK. The measuring elements function according to the double beam principle. The acting forces are captured by strain gauges applied to the measuring elements. HAEHNE offers for all its sensors a corresponding range of amplifiers to condition the measuring signal and deliver the bridge voltage supply. The signals at the output terminals of the amplifier are proportional to the acting horizontal force. They can be digitally displayed or used as instantaneous values in a closed control loop.
