Gems Sensors has reduced the size of its electro-optic level sensors by 50%, with the introduction of the ELS-1150 - which measures just 35mm long.
The ELS-1150 electro-optic liquid level sensor combines the high performance environmental capabilities of its larger family members with a reduction in size of 50%.
Measuring just 35mm long, the new ELS-1150 is the smallest electro-optic sensor in its performance class and is extremely economical.
Unlike competing optical sensors, the ELS-1150 uses a strong glass prism - fused to a nickel-plated carbon steel housing.
This allows the monitoring of vessels, pressurised up to 170bar, while also deflecting the troublesome build-up of droplets associated with conventional 'dome-type' sensors.
The operating temperature range is a broad -40 to +100C.
The high performance and compact size of the ELS-1150 makes it ideal for monitoring the small pressurised vessels found in HVAC, refrigeration and hydraulic applications.
They are most commonly used for low, high and immediate level detection.
The glass prism works in conjunction with infrared LED and TTL/CMOS-compatible solid-state circuitry to provide reliable liquid level detection and a transistor-based switch action, with no moving parts.
Units are capable of switching 18mA.
Currently available with 0.5in NPT mountings, the ELS 1150 will also be available with other mountings in the near future.
Installation is easy, as the bodies themselves form a 0.875in hex.
They are available with wet or dry sinking (NO or NC and operating voltages of either 5 or 12V DC).
