SPK Contact unit

Features

The contact unit of the SPK range is used for fluid level monitoring through zero contact magnetic actuation of a contact. The contact unit consists of one or more magnetic elements which transmit the position of the fluid level or of the pressure booster piston rod to the switches without touching. The switches are reed contacts or inductive contacts in accordance with NAMUR.

SP23 Flow meter

Flow meters of the SP23 range are used for checking the amount of fluid used to refill the barrier fluid circuit in closed systems (e.g. SPN1000/3000). The indicated volume equals the amount lost from the circuit through leakage.
