Gems ELS-1100HT Series Single-Point Level Switch is the high-temperature version of the ELS-1100 and is made from high-performance Isoplast plastic. While maintaining broad chemical compatibility, these units also handle fluid temperature to 212°F (100°C). They feature 3/8″ NPT mountings and are 1/2″ long.
| Gems ELS-1100HT / ELS-1100HTS Electro-Optic Level Sensor (High Temperature) Technical Specifications | |
|---|---|
| ● GENERAL | |
| Description | Slightly larger than the standard ELS-1100, the “HT” (High Temperature) version is made from high-performance Isoplast® plastic. While maintaining broad chemical compatibility, these units handle fluid temperatures to 212°F. They feature 3/8″ NPT mountings, and the “HTS” (Short) version is the shortest of any Gems plastic electro-optic switch body — a mere 1/2″ long. UL Listed, File No. E108913. |
| Typical Applications | Coolant reservoir monitoring; medical diagnostic and sterilizer equipment; low lubricant warning on machine tools; low level warning in hydraulic reservoirs. |
| ● SPECIFICATIONS | |
| Materials — Housing and Prism | Isoplast®. |
| Operating Pressure | 0 to 150 PSI, maximum. |
| Operating Temperature* | -40°F to +212°F (-40°C to +100°C). |
| Current Consumption | 45 mA, approximately. |
| Output | TTL/CMOS compatible. Transistor output with 10K pull-up resistor may sink 18 mA. 12 VDC input power units switch a maximum 5 VDC on output. |
| Repeatability | ±1 mm. |
| *These switches are not for use in freezing liquids or steam/high condensation environments — contact Gems for alternative solutions. | |
