Monitoring devices
There is always plenty to monitor in industry, residential and non-residential buildings. Whether dusk or temperature, voltage or current loads – our monitoring devices can be used in a huge range of applications and offer a wide variety of protective functions.

  Sensors
  Fault signaling units
  Switches and controllers
  Controllers
  Circuit relays
  Relays

Bells and buzzers


Bell or buzzer with 230 V AC connection in a single device
Alternative operation over a pushbutton with safety extra-low voltage 12 V AC
Fast response possible due to "audible" faults or limit value signals

 
 
Fault signaling units


 
For the evaluation and display of fault or alarm signals
For monitoring industrial plants and control units
Allow the configuration of a complete fault signaling system with four fault signal inputs and up to 39 additional fault detectors each with four fault signal inputs and a centralized alarm function

 
 
Switches and controllers


 

 
Dusk switches
Saving of operating costs through demand-oriented switching of lighting installations for shop windows or paths
Reduction of installation costs as only one light sensor is required for 24 separately adjustable switching channels

 
 

Temperaturregler

 
Temperature controllers
For heating registers, panel and hot air heating and direct floor heating, as a limiting thermostat for air-conditioning systems and cooling systems, switchgear cabinet cooling, etc. as well as for temperature control in humid and dusty rooms
Expanded temperature range up to 400 °C for even more options

 
 

Vorrangschalter

 
Priority switches
In mixed operation of electric hot water and electric storage heaters, interrupts the charging procedure of the storage heater if hot water is required during the low-tariff time, thus limiting the connected load.

Monitors


Sicherungswächter

 
Fuse monitors
For monitoring all types of fuses
For signaling failure, even in systems that are switched off, thus increasing plant availability
For protecting downstream three-phase AC loads against damage, as automatic shutdown is possible in the event of a single-phase failure

 
 

Phasen und Drehrichtungswächter

 
Phase and phase sequence monitors
For monitoring and indication of phase failure and direction of rotation in 3-phase systems

 
 

Isolationswächter

 
Insulation monitors
For monitoring the insulation resistance in non-grounded power installation supplies, in underground mining, open-pit mining and quarries
Designed for AC operation or DC operation in the measuring ranges 100 k? or 200 k?, its protective function can be compared to that of a residual current protective device

 
 

COS phi Wächter

 
Power factor monitors
For the monitoring of low loads in motors in the event of a V-belt breakage, for pump monitoring on dry runs and for filter monitoring in the event of a filter blockage or valve closure

 
 
Circuit relays


Netzkoppler

 
Switching off of unused lines or plant components
Prevention of detected safety hazards due to electromagnetic fields

 
 
Relays

Spannungsrelais

 

Voltage relays
For monitoring the voltage supply of emergency lighting in public buildings
For monitoring the voltage supply for short-time failures of 20 ms
For safeguarding operating parameters for devices or plant components
For monitoring the neutral conductor for breaks

 
 

Stromrelais

 
Circuit relays
Switching off of unused lines or plant components
Prevention of detected safety hazards due to electromagnetic fields

 
 

Niveaurelais

 
Level relays
Level monitoring and control of conductive liquids and powders, e.g. maximum and minimum levels, overflow and dry run protection
Monitoring and control of the mixture ratio of conductive liquids
Large measuring range of 2 to 450 kO permits differentiation between foam and liquid and ensures reliable operation

 
 

Motorschutzrelais

 
Current relays
Monitoring of emergency and signal lighting according to DIN VDE 0108, for position lighting in approach corridors or runway lighting
Protection of motors before they can overheat
