Function Description Function Description 20 Functional Principle 20.1 General The 2-wire pressure probe is used to measure static and dynamic pressures of gaseous and liquid media. Relative pressure (negative and positive pressure) as well as absolute pressure can be measured. The pressure is converted into a standardised electrical signal.
Technical Description Pressure/Level Probes Installation, Mounting and Connection 21 General Installation Instructions Before commissioning the installation of pressure and level probes must be com- pleted. Verify whether the installation is correct. Observe that the installation shall be carried out only by qualified expert personnel. For electric installation the legal requirements of the according country must be followed (in Germany: e.g.

Installation, Mounting and Connection Note Use suitable tools to install the units and do not use force. Tighten cable glands carefully. For hanging probes, remove the protective cap (Fig. 25-1), as this serves only as transport protection. The protection class of the housing is IP65/IP67 for pressure probes with screw-in thread (½"...
When using the probe in conjunction with NIVUS Ex-GPRS data loggers of the types NivuLog Easy and NivuLog 2 Ex (N), connect the shield to the GND/ground terminal.

Technical Description Pressure/Level Probes Commissioning Notes to the User Before connecting and putting the pressure or level probe into operation, it is es- sential to observe the following instructions for use! This instruction manual contains all information required for the use of the probes. The instructions are intended for technically qualified personnel who have relevant knowledge in the field of measurement technology and waste water hydraulics.
In addition to the annual maintenance, NIVUS recommend a complete mainte- nance of the measuring system by the NIVUS customer service after ten years at the latest. Generally, the verification of sensors and probes is a basic measure in order to im- prove operational reliability and to increase the lifetime.
Technical Description Pressure/Level Probes 25 Cleaning If necessary, clean the probe enclosure with a slightly damp lint-free cloth. Static Charge There is a risk of static charge when cleaning with a dry cloth. For heavy soiling, the use of wetting agents (standard dishwashing detergents) is recommended.
The installation and/or use of such products may therefore negatively alter or invalidate the design properties of your measurement system. NIVUS are not liable for damage caused by the use of non-original parts and non- original accessories. Probes AquaBar / UniBar E - TB - Rev. 10 / 22.12.2022...
