Pneumatic timers are small and lightweight

TME has introduced a range of pneumatic time relays from Crouzet, with time ranges of 0.1 to 30 seconds and NO or NC outputs, in which voltage is replaced with pneumatic pressure/technical air.

Time value setting is done by an embedded potentiometer that ensures an accuracy of +/-5 per cent.

Models available include the Crouzet 81503540, with positive NC output and the time of 0.4sec; Crouzet 81506540, with negative NO output and the time of 04sec; Crouzet 81503710, with positive NC output and the time of 0.1 to 15sec; Crouzet 81506710, with negative NO output and the time of 0.1 to 15s; Crouzet 81503720, with positive NC output and the time of 0.1-30sec; and Crouzet 81506720, with negative NO output and the time of 0.1 to 30s.

The two first models have fixed time ranges without the possibility of adjustment, while the other models allow adjustment of time delay within the given ranges.

Each model features nominal working pressure of 2-8 bar; 170Nl/min flow at 6 bar pressure; minimum reset time of less than 0.1sec; nominal operation temperature of 5 to 50C; mechanical durability for around 10 million cycles; and M4 process connection.

Small sizes, small weight and high mechanical durability make this equipment suitable for use in the majority of complex pneumatic systems and everywhere where pneumatic time delay is necessary.
