- Product Description
-
This instrument is composed of armored vibration-resistant platinum resistance or thermocouple combined with a dedicated transmission circuit, which can convert the temperature signal of the sensitive element into a standard signal output on-site, without the need for compensating wires, enabling long-distance transmission. Within the rated operating range, the signal accuracy is independent of load resistance and supply voltage, making it easy to connect with various instruments and computer systems.
The main features of the instrument are as follows:
- (4～20)mA output is linear with temperature
- High detection accuracy and long-term stability
- Uses specially made armored platinum resistance, good shock resistance and corrosion resistance
- IP66 protection level, suitable for outdoor installation
- Explosion-proof Ex db IIB T6 Gb, Ex ia IIC T6 Ga
- Has lightning protection and radio frequency interference protection circuits
- Can be equipped with an LCD digital display or a pointer display for on-site temperature indication
- The display can be rotated 360° to adjust the viewing direction;
- In high-temperature environments, the transmission circuit can be installed separately from the temperature sensor
- Output RS485 Modbus protocol
- Output signal can superimpose HART protocol digital signal (optional)
