Function

of digital accelerometers ZET 7052-N

Digital accelerometer ZET 7052-N is equipped with a compact sensing element and is designed for linear acceleration and vibration acceleration variable constituent measurement via three mutually perpendicular planes.

Small weight of sensing element (1,5 g) considerably reduces self-mass load and compact dimensions (8,5×8,5×8,5 mm) enable use of the digital accelerometer  ZET 7052-N for vibration measurements in systems with small active area.

When installing  ZET 7052-N one should observe direction of measuring axes (shown on the casing of the sensor).

The sensors are mounted on the measured object or inside of the electrical cabinet together with interface modules providing data transfer.

ZETLAB electrical cabinet has compact dimensions if compared with available analogs. Among  ZETSENSOR modules advantages one can mention easy mounting and de-installation as well as power indication and signal transfer, which makes it easy to perform on-site system diagnostics.

Operating principle

of digital accelerometers ZET 7052-N

Digital accelerometer ZET 7052-N is a vibration sensor with an integrated triaxial sensing element converting constant component of vibrational acceleration into digital code in three mutually perpendicular planes  X, Y and Z.

Vibration velocity and vibration displacement values are calculated by integrated processor. Calculation of average value is performed as an average for linear acceleration and as RMS for all the rest parameters.

Explosion-hazard areas – application requirements

for digital accelerometers ZET 7052-N

When using digital sensors in explosion-hazard areas one should observe applicable national requirements.

It is allowed to place digital sensors in explosion-hazard areas only in the case if this sensor is made for application in explosion-hazard areas and has corresponding mark on the casing – 0ExiaIICT6 Х.

In order to provide connection via data channels and power supply lines, the digital sensors should be connected to the interface converters via intrinsic-safe barriers placed in explosion-hazard areas. Typical connection scheme of digital sensors placed in the explosion-hazard areas is shown in the figure below. Recommended intrinsic-safe barriers types are shown in the corresponding chart.

Measuring network scheme

based on digital accelerometers ZET 7052-N

Digital accelerometers ZET 7052-N have two 4-contact connectors for connecting to the measuring network (the delivery scope includes mating couple).

Contact number Designation
1 +(9…24) V
2 RS-485 line «B» or «DATA-»
3 RS-485 line «A» or «DATA+»
4 GND

Using  ZETSENSOR one can establish distributed measuring networks, control systems, automated equipment complexes. For connection of the measuring networks to the systems ZETLAB and  ZETVIEW interface converter ZET 7070 is used.

Amount of the digital sensors connected to ZET 7070 module using integrated power supply unit ZET 7070 — is maximum 3, in the case of use of external power supply unit – not more than 60. ZETLAB software supports connection of up to 1024 sensors to a single PC. Measuring networks can also be connected to any type of the system using Modbus protocol via interface RS-485.

The figure below depicts ditributed measuring system using digital accelerometers ZET 7052-N with an integrated measuring unit connected to the ZETLAB system.

Control of digital accelerometers ZET 7052-N

Digital sensors are ready for operation – all necessary setting are stored in the sensor memory. In the case if it is necessary to configure settings (for instance, due to the change of the primary transducer), one should connect the sensor to the PC using interface converter, start ZETLAB software and Device manager. The settings can  be configured in the tab “Sensor”.
