Product Specs

Layer N SS-002 Smart Sensors provide an external 3-wire RTD, thermocouple, or contact closure solution in addition to the built in suite of precision internal sensing elements that come standard with the SS-001 to accurately measure environmental conditions for a wide range of applications. The SS-002-0 offers a configurable choice of an external thermocouple, RTD, or DIN (contact closure). The SS-002-1 offers a configurable mix of any three of the four internal sensors: Temperature, Humidity, Barometric Pressure, Ambient Light, AND one external sensor option: Thermocouple, RTD, or DIN (contact closure).

Long Range

The SS-002 utilizes Sub GHz Frequency Hopping Spread Spectrum (FHSS) technology to ensure robust, long range communications. Transmission ranges of up to 1.2 km can be achieved with the standard AA batteries and transmission ranges of up to 3.2 km can be achieved when powered by a standard 5V micro USB cable2.

Plug and Play

Layer N Smart Sensors are easily paired to the Layer N Gateway with the press of a button, and will automatically show up on your Layer N Cloud Account. The Layer N Gateway can connect up to 256 Smart Sensors4 per unit. Local data logging keeps your data secure in the event of a power or network outage. Reports, History, and E-mail alerts from the Layer N Cloud keep you informed on the status of all your vital processes.


Layer N wireless products are designed with state of the art security features to protect your data with robust AES256 encryption and advanced PKA-EC521bit (NIST) elliptic-curve cryptography to protect your data.

Advanced Features

Advanced Omega Level N features may be configured through SYNC software and include selective data extraction, measurement and device traceability, local alarms and adaptive transmission rates to reduce data congestion and extend battery life.

I am considering SS-002-0-NA for monitoring ovens via RTD within a laboratory. Does the unit ship with a calibration certificate and does Omega offer services for future calibrations?

Is it compatible with XC-14-K-12 thermocouple ? Does it need other accessory ?

Asked by: Fadhel
Because the probe has 14 AWG wire it is quite large and you may want to use a pigtail to connect. A OSTW-K-M on the probe and OSTW-K-F and a small length of K type Thermocouple wire will do the trick.
