ULTRA Industrial Wireless Water Temperature Sensor with 25 Foot Probe (900 MHz)
Part Number: E2ES2-9-IN-TS-WT-L25$265.20
E2E wireless water temperature sensor use a 3 foot external water sealed sensor probe to measure temperatures in water or non-combustible liquids. Perfect for monitoring temperatures in water storage tanks, pools, aquariums and natural wet-life environments. User customization allows you to set the frequency of readings and the ability to set conditions for text and/or email notifications from the system.
Product Information
ULTRA - Leading Enterprise Grade "Internet of Things" Solutions
ULTRA sensors offer 3 to 4 times the range of standard sensor platforms, extending non-line-of-sight reach to an exceptional 1,200+ feet through walls (12-14 walls typical). Using Frequency-hopping Spread Spectrum (FHSS) also allows ULTRA sensors to have better interference immunity from other wireless devices.
Superior power management provides ULTRA sensors with almost twice the battery life of E2E’s standard wireless sensors.
- Coin cell sensors typically last 3+ years.
- AA and Industrial sensors typically last up to 12+ years.
Integrated on-board data storage allows ULTRA sensors to store data messages if communication to a wireless gateway is disrupted (power outage, Internet outage, or out of range). Messages that can’t be delivered will be time-stamped and stored in memory (up to the last 512 messages) until communication with the gateway is restored, at which point the messages will all be transmitted.
Over-the-air updates allow ULTRA products to be updated remotely if new fixes or features become available.
E2E ULTRA Industrial Sensors come in an IP65, NEMA 4X, CE rated, sealed, and weatherproof enclosure. They are powered by a single, replaceable, Industrial grade 3.6 V battery (included).
An optional solar powered version is also available. The solar powered version includes a Lithium Iron Phosphate rechargeable battery in conjunction with a solar power cell to keep the battery charged and at optimal capacity. If there is no light present at the solar cell, the battery alone could continue to power the sensor for up to 8-10 years.
Product Features
