Field of application
The economical Soliswitch FTE20 is a paddle switch for point level detection in bulk materials. Its robust polymer housing and compact design makes it an ideal sensor for full, empty and demand alarm in applications with bulk solids. The optimized polymers make the unit outstandingly robust and therefore suitable for use in dust explosive areas according the latest standards.
Process connections: NPT 1½”, PBT; NPT 1¼”, PBT; G 1½”, PBT; NPT 1½”, 1.4305; NPT 1¼”, 1.4305; G 1½”, 1.4305
Sensor length: Different standard lengths between 100 mm (4″) and 600 mm (24″), additional rope length of 2000 mm (80″) (can be shortened)
Medium temperature: -20 to +80 °C (-4 to +170 °F)
Process pressure range (absolute): 0.5 to 2.5 bar (7 to 36 psi)
