More than 75 years of solutions - carlo gavazzi
Carlo Gavazzi was a man who saw a future in automation in the days when it was seen by most as pure science fiction. The history of the business is littered with firsts and Carlo Gavazzi Automation Components are today installed in a huge variety of state-of-the-art, hi-tech products and processes all over the globe.
Capacitive Sensors
Carlo Gavazzi's patented Tripleshield™ Capacitive Sensors have become the standard all other manufacturers are measured against. All Tripleshield™ sensors are tested to withstand electrostatic discharges up to 40 KV, line transients up to 4 KV, and airborne noise (ie. cellular phones) up to 15 V/m. Furthermore, some models have built-in humidity compensation.
Capacitive Proximity Sensors
Capacitive proximity sensors will detect most materials - conductive and non-conductive. This makes them ideal for level detection in raw plastic delivery systems and in agricultural applications.
Our sensors are available in 12 mm, 18 mm, and 30 mm diameter with both AC and DC outputs. We offer both plastic and metal housings with either a built-in cable or a connector.

Our products include current monitors, voltage monitors, power monitors, phase loss relays, and current transformers.
These monitors are used in a wide range of applications for protecting motors against the damaging effects of single phasing and overloads (elevators, compressors, pumps, air conditioning systems, mixing tanks). They are also used extensively for monitoring instrumentation signals (4-20mA, 0-10V), verification of machinery operation, detection of broken heater elements, monitoring of lights in critical areas (runway lights at airports), monitoring of ventilation fans, and in building automation systems.
Digital Panel Meters
Carlo Gavazzi offers a comprehensive range of digital panel meters and digital displays (current meters, ammeters, voltmeters, frequency meters, temperature meters and temperature controllers, tachometers, and rate meters) for the OEM, Panel Builder, Instrumentation, and MRO customer. Covering most input types (current/voltage/temperature/resistance/RPM), our digital panel meters are well suited for your display requirements.
The UDM series is a hi-tech modular panel meter family developed to meet your most advanced application needs. The series is available with either a 3 1/2 digit (UDM35), 4 digit (UDM40), or 6 digit (UDM60) display. It can also be ordered without a display and be used as transducer or signal conditioner (USC).
The UDM series accepts most signal inputs (current, voltage, temperature, tach) and offers an analogue output as well as up to 4 digital outputs (relay). Since these are modular meters, outputs can be added at any time in the field. Remote monitoring via a PLC or PC is possible by inserting an RS485 communication module into the meter. In this way many meters can be monitored without adding a lot of expensive analogue cards to your PLC.
The UDM40 meter also features a 3-colour display allowing at a glance indication of relative operating condition (OK - Green, Caution - Yellow, or Alarm - Red). Furthermore, the UDM40 is also able to handle and correctly display non-linear signals. THe UDM60 series is for displaying pulse type signals (frequency, RPM, period measurement, and counters). The dual inputs and dual LCD display allow simultaneous display (digital and analogue) of both inputs.

Dupline
Dupline® - the versatile bus for Industrial Applications and Building Automation. Dupline is used for transfering analogue and digital information over distances up to 10 km. It can be used stand-alone or as part of a PLC based control system. There are no special protocols to learn - all modules are simply and quickly configured with a small hand-held device.
Dupline is used extensively in mining (ventilation, lighting, and conveyor control), elevators (for signal transmission), irrigation systems, water treatment facilities (signal monitoring, control), facility alarm systems, and in building automation (temperature and lighting control, security).
The nature of our voltage mains has changed greatly in the last 10 years. With the proliferation of non-linear loads such as inverters, power converters, switch-mode power supplies, and computers, there is a growing concern for the quality of our power sources.
Problems often arise which can cause equipment failure or shutdown resulting in significant costs and loss of production. Power quality problems can result in failure of compensation capacitors, tripping of fuses, over-heating of transformers and motors, failures of electronic equipment, and high neutral currents.
Energy costs are becoming a significant expense in most processes. With increased energy unit costs, decreased generating capacity, and the environmental concerns with the burning of fossil fuels, it is important that companies reduce their electrical consumption.
Energy/Quality Power Meters
Carlo Gavazzi offers a broad range of power quality meters, energy meters, and transducers which give early warning of power quality problems - allowing preventative action to be taken before a major failure results. Most of our products offer relay outputs that can be used to immediately shut down a piece of equipment if a certain threshold is reached. Another option is to connect to your PLC or PC control system to provide plant wide monitoring of power quality using 4-20 mA current signals or via RS485 communications.
In addition to our broad range of energy meters and power quality meters, Carlo Gavazzi also offers a number of software products for monitoring of a network of meters and transducers. This allows at-a-glance viewing of your complete power system
