ATxBlock Temperature Transmitter |
View
Large
|
The ATxBlock is a 2-wire in-head temperature transmitter, microprocessor based designed for the flexibility of accepting mV, Pt100 and a variety of thermocouples as the input sensor. The ATxBlock delivers a scalable linear 4-20mA or 0-10V output signal proportional to the sensor temperature. User-friendly configuration software is provided for parameter set up, including sensor type, temperature range, filter, etc. |
 |
| Sensor Input | : | User defined. The supported sensors are listed in ATxBlock Catalogue, Input Sensors, along with their maximum ranges and minimum span.
| | Thermocouples | : | Types J, K, R, S, T, N, B and E according to IEC 60584 (ITS-90) | | Pt100 | : | Excitation: 180 µA.
2 or 3-wire connection ( for 2-wire sensors, tie terminals 2 or 3 together ).
α = 0.00385, according to IEC 60751 (ITS-90). | | Voltage | : | 0 ~ 50 mV DC.
Impedance: 1 MΩ | | Total Accuracy | : | Better than 0.25% of the maximum range for Thermocouples and 0.15% for Pt100 and Voltage. | | Response Time | : | < 100 ms | | Output | : | 2-wire 4-20 mA, linear with respect to the measured temperature | | Resolution | : | 0.004 mA (12 bits). | | Power Supply | : | 12 to 35 Vdc, across the transmitter | | Maximum Load (RL) | : | RL (max.)= (Vdc – 12) / 0.02 Ω
Where: Vdc= Power supply voltage | | Operating Temperature | : | -40 to 85 °C | | Humidity | : | 0 to 90% RH | | Electromagnetic compatibility | : | EN 50081-2, EN 50082-2 | | Polarity Inversion | : | Internal Protection | | Isolation | : | No isolation between the sensor and the 4-20mA loop. | | Misc. | : | Cold junction compensation for thermocouples. |
