This document provides detailed information on all four models of Flowline Switch-Tek™ powered level switches; Vibration (LZ12 series), Ultrasonic (LU10 series), Optic Leak (LO10 series) and SuperGuard Capacitance (LP15 series), including their specifications, sensor information, installation, electrical etc.
The document provides a comprehensive guide for the Switch-Tek™ Powered Liquid Level Switches, covering four distinct series: Vibration (LZ12), Ultrasonic (LU10), Optic Leak Detection (LO10), and SuperGuard Capacitance (LP15). All models feature two outputs: a 4 or 20 mA current switch and a 60VA SPST dry contact relay, manufactured with thermoplastics for submersible use in corrosive applications.
| Supply voltage | 12-36 VDC (LZ12 Only: 12-30 VDC) |
|---|---|
| Contact rating | 60VA (125 VAC max / 1A max) |
| Accuracy | ± 1 mm in water |
| Repeatability | ± 0.5 mm in water |
| Process temperature range (F) | -40° to 176° F |
| Pressure rating | 150 psi (10 bar) @ 25 °C. |
The LP15 series is factory-calibrated to be used with liquids having a dielectric value between 20 and 80.
The sensor is factory-calibrated to be used with liquids that have a dielectric value between 20 and 80.
Liquids with a dielectric constant less than 20 will not be detected by an LP15 series sensor.
The LZ12 series requires a supply voltage of 12-30 VDC.
