ULTRA Industrial Wireless Low Temperature Sensor (900 MHz)Part Number: E2ES2-9-IN-TS-LT-L03
E2E wireless low temperature sensors use an RTD to accurately measure temperatures from -200°C to +162°C. Perfect for low temperature critical applications such as freezers and coolers. User customization allows you to set the frequency of sensor readings and create notifications from the system when certain criteria have been met or exceeded.
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.
- Accurate to +/- 0.3°C @ 0°C.
- RTD temperature range: -200°C to +162°C (-328°F to +325°F)
- Good for extremely low temperature applications.
* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables.
