B59300M1110A070 Cross PTC Thermistors As Limit Temperature Sensors 110C

AMPFORT PTC sensors feature a particularly steep R/T characteristicscurve. PTC sensors with the same or differing nominal response temperatures can also be switched in series.This makes it possible to monitor machine and coil parts with different limit temperatures at low cost. Various nominal responsetemperatures are available.The PTCs provide for a secure switch-off in conjunction with aseparate evaluation when the nominal response temperatures arereached.The structural design makes it possible to achieve short thermalresponse times and facilitates the installation.

PTC sensors according to DIN VDE V 0898-1-401 are used to protectelectrical machines against thermal overload.

5.Operating Instruction

The electric motor of different insulation rank selects the different Tk temperature thermistor, its parameter is shown at following table(only reference).

6.Note for mounting

1.Insert wire in the winding wire slot of the motor,make it tidy, and then mount the PTC thermistor in the coil of motor(as shown in figure).

2.White mounting,do not hard beat or press the sensing area of the thermistor for fear that the internal precise structure of the product might be damaged.

3. While mounting,do not extremely hard pull the outgoing line of the product for fear that the outgoing line might be pulled apart.

4.Before connecting,read the technical information about PTC temperature control module(the former GRB motor overheat protector) for fear that the thermistor might be damaged.

5.Securely connect the outgoing line in the specified connection position.

9. OPERATION

PTC thermistors exhibit very high sensitivity over a narrow temperature band. For temperature measuremen in this range, NTC thermistors are easier to measure and more accurate. PTC thermistors are especially suited as temperature sensors for monitoring the windings of electric machines, and also for use in simple fail-safe circuitry. When a given temperature (nominal response temperature qNAT) is exceeded, the circuit can be switched off through a relay or amplifier, since the PTC-sensor will have an extremely high ohmic value in the region of its response temperature. This will have the same effect as a break in the circuit or a failure of the thermistor.

10.INSTALLATION TIPS

For PTC temperature sensors in electrical windings:

- the thermistors can only be inserted in the windings before impregnation - it is advisable to embed one in each phase, if possible in the centre of the coil generating most heat, and generally on the outflow side of any air movement

- air inflow onto the temperature sensor will interfere with heat transfer

- if using varnish/lacquer which is not chemically neutral, suitability tests must be undertaken by the customer

- WARNING! It is very important that the sensor must be installed parallel with the copper of the winding, so that the PTFE leads can assume the form of the rest of the winding and thereby retain the high- voltage resistance rating.
