Wireless Probe Temperature Sensor
Precision wireless temperature measurement with external probes for pipe surfaces, immersion wells, and contact applications. Monitor heating and cooling systems, process temperatures, and cold chain environments.
Versatile Probe Options for Any Application
The TES series uses external temperature probes connected via standard connectors, allowing you to select the right probe type for your application. Pipe-strap probes clamp directly onto heating and cooling pipes for non-invasive surface temperature measurement. Immersion probes insert into thermowells for direct fluid contact in tanks, ducts, and process vessels. Cable probes provide flexible placement in confined spaces, cold rooms, and equipment enclosures where rigid probes cannot reach.
Precision Temperature Measurement
The TES series delivers high-accuracy temperature readings using calibrated PT1000 or NTC thermistor probes. With a measurement accuracy of +/-0.5°C across the operating range, the TES provides the precision required for HVAC performance monitoring, process control verification, and cold chain compliance. The 12-bit ADC resolution ensures smooth, noise-free temperature data with fine granularity for detecting small temperature changes over time.
Two Independent Probe Inputs
Each TES unit accepts two independent temperature probes, enabling simultaneous measurement of two points from a single device. This is particularly useful for monitoring heating system flow and return temperatures from a single unit, or tracking temperature at two nearby locations within a cold room or process environment. Both channels report independently to the gateway, with individual alarm thresholds and reporting intervals configurable for each.
TES-1X and TES-2X Variants
The TES-1X provides a single probe input for applications where one measurement point is sufficient, offering a compact and cost-effective solution. The TES-2X provides two independent probe inputs for dual-point monitoring such as flow/return temperature pairs. Both models share the same DIN-rail form factor, wireless interface, and configuration options, making it simple to select the right variant for each measurement point in your deployment.
