Probes and Damping Blocks

Accessories for Temperature Data loggers

Our probes connect easily to Vaisala data loggers. The Vaisala EPT series external temperature probes for data loggers include the N and V models. The N model probes have an operating/storage range of -40°C to +95°C. The V range external probe's operating/storage range is -95°C to +95°C. Initial accuracy is ±0.10°C over +20 to +30 °C. Sensor Tips come in stainless steel, liquid submersible sealed Teflon tip and probe length can be 3 m (10 ft) or 7.6 m (25 ft).

Overview

The Vaisala external temperature probes (EPT) are epoxy-encapsulated NTC thermistor, or RTD, with a stainless steel tip. Probes come in 10 ft. (3m) or 25 ft. (7.6m) lengths and are calibrated with a data logger as a complete unit to ensure optimal accuracy. Find EPT probe specifications on the DL1000-1400 data sheet.

Optional thermal damping blocks help ensure accurate and stable temperature measurements and are ideal for refrigerator and freezer monitoring applications. These blocks were designed to match the temperature curve of a bottle filled with glycol as a buffer against false alarms and to provide a temperature measurement more similar to stored product, rather than air. The thermal mass of the block provides a damping effect that eliminates nuisance alarms that can be caused by temperature fluctuations.
