| Temperature data logger for 3x thermocouples, 1x external Pt1000 probe and 1x internal sensor | COMET SYSTEM, s.r.o | TECHNICAL DATA MEASURED VALUE Temperature TEMPERATURE SENSOR - INTERNAL PROBE Measuring range -30 to +70 °C Accuracy ±0.4°C; Resolution 0.1 °C Response time of temperature measurement (temperature step 20°C, air flow approximately 1m/s) t63 < 6 minutes; t90 < 15 minutes TEMPERATURE SENSOR - EXTERNAL PROBE PT1000 Measuring range -200 to +260 °C Accuracy ±0.2°C; ±0,2 % of the measurement value in a range of +100 to +260 °C Resolution 0.1 °C Response time t90 of temperature measurement (temperature step 20°C, air flow approximately 1m/s) according to the connected probe TEMPERATURE SENSOR - THERMOCOUPLE TYPE B, J, K, N, S, T Measuring range according to the connected thermocouple Accuracy ±0,4°C Resolution 0,1 °C Response time according to the connected thermocouple | Mai mult | |
| Web Sensor with PoE - two channels with flood detector and binary inputs | COMET SYSTEM, s.r.o | P-line Web Sensor with PoE for measuring temperature, and relative humidity, with flood detector and binary inputs for two-state signals. Web Sensors P8653 is designed to measure temperature or relative humidity from up to two external probes. This allows to measure values from two different places by one device. The device is equipped with three binary inputs. P8653 has a dedicated first binary input for connection of flood detector LD-81 (included). Other two binary inputs can be used to connect dry contacts or binary sensors with voltage output. Communication with the device is realized via the Ethernet network. P8653 can be powered from an external power supply adapter or by using power over Ethernet – PoE. Processing and analysis of measured data: online in COMET Cloud COMET Database software integration into 3-party systems code P8653 Warranty 3 years In stock on request | Mai mult | |
| COMETEO Professional Thermometer Screen for Weather Station Sensor | COMET SYSTEM, s.r.o | Professional radiation shield for protection of temperature sensors or combined temperature/humidity sensors, weather monitor, and data logger. Passive, naturally ventilated. "Not only thermometer screen, but the complete COMETEO system minimizing measurement errors when used with high-quality certified sensors" The multi-plate radiation shield is used to protect weather monitor systems and provides the most accurate climate measurement results. The uniquely designed screen minimizes solar radiation reaching the sensor, minimizes radiation absorbed by the screen, and maximizes ambient airflow around the weather station sensor. The surface exposed to sunlight is made of highly reflective UV and long-term stable ASA plastic. The inner surfaces of the screen are made of matt black plastic to minimize internal reflections. The large 210mm diameter of 14 plates is designed to provide full protection of the weather sensor. Each of the fourteen black louvers is equipped with a circular slot allowing air to flow vertically through the entire radiation shield. The slot also separates the sunlit part of the louvre from the inner part and thus prevents heat transfer to the sensors. Cylindrical space with 110mm diameter and 210mm height is available inside of the plates for installation of the entire climate measuring device with minimized solar radiation. Excellent wasp and bug deterrence. Sophisticated design prevents insects from building nests inside and thus degrades measurement. Low-cost stable replacement for Stevenson screen, taking advantage of reduced maintenance and better performance due to the low time constant compared to the traditional Stevenson screen. Works with COMET instruments and most professional weather equipment. | Mai mult |
