PTC THERMISTOR RELAY
ZIEHL PTC-resistor relays protect motors, transformers, machines and equipment against thermal overload. With ZIEHL PTC Sensors MINIKA ® applied they offer best solutions for nominal response temperatures 60°C…180°C.
ZIEHL PTC-resistor relays are designed for PTC-sensors according to DIN 44081 and DIN 44082. Therefor sensor and relays are exchangeable. PTC-resistor sensors are suitable for the installation into windings of electrical machines, bearings and transformers as well as to monitor the temperature of liquid media, airflow and gases.
WEB CONTROL
Devices with Ethernet interface can be connected to the Intranet / Internet and operated with a browser. Data are available via Modbus TCP/IP. If limit values are exceeded, an alarm is triggered by relay and e-mail.
PTC THERMISTOR RELAY FOR DRY TRANSFORMERS
Do not generate a tripping pulse when activated. Simple versions up to variants with integrated fan controller and fan monitoring are available.
PT100 & THERMOCOUPLE
Type TR devices monitor and control temperatures.
Up to 12 sensors, 7 switching points, digital displays, differential temperature monitoring and analogue outputs open up a wide range of potential applications.
Also for Pt1000, KTY 83/84 and PTC sensors.

PTC SENSORS
PTC-resistors are used principally to protect windings in electromotors or transformers against excess temperature. They also find application in machines, tooling machines especially machine bearings and controlling the temperature of power semiconductors.
TEMPERATURE SENSORS (PT100)
PT100 for use with switchgears, measuring transducers and display units. Designs for winding installation, as screw-in, immersion or room temperature sensor.
