Switch-Pak AX1X High or Low Liquid Level Switch with Junction Box
The intrinsically safe or general purpose level switch package provides high or low liquid level detection with one relay or reed switch output, and a compact junction box for wiring termination. Available in three level sensor technologies, choose the sensor type based upon your application media and classification. Select ultrasonic for chemicals and light weight oils; vibration for wastewater with light coating or scaling; and buoyancy for clean water and non-coating chemicals. This PP or PVDF level switch package is selected for bulk storage, IBC or drum, and neutralization tank applications, connected to a PLC or relay controller.
