Liquid Level Controller V4LM4S30 24–240V AC/DC
Two wires from the relay are connected to a resistance-sensing probe in the pump seal cavity and the grounded motor housing to monitor for seal leakage, applying an ultra-low voltage signal.
If the seal starts to leak, contaminating fluid enters the seal cavity. This lowers the resistance between the internal probe and the common ground. When the resistance drops below the user-adjusted sensitivity setpoint of the relay, the output relay energizes, visualizing the current condition of the seal with an indication LED on the front of the device. The relay output can be used to give an alarm indication of a leaking seal.

Tiny, low profile, 150W AC-DC power supply from XP Power features medical (BF) and ITE approvals.
XP Power has announced its EPL150 series, a range of high density, low profile, open-frame AC-DC power supplies aimed at space-critical, cost-sensitive, industrial, ITE and healthcare applications.
The EPL150 series produces 100W output with convection cooling and 150W with as little as 10CFM airflow. The product has a 101.6 x 50.8mm footprint and its low profile of 25.1mm makes it ideal for space-constrained applications. Class-leading power density is enabled by high efficiency, up to 95% typical at 150W with better than 85% achieved down to 10% load. No load losses are less than 0.5W giving reduced running costs and compliance with the latest environmental goals and legislation.
