RZ13 Series Temperature Transmitter
Product Details
RZ13 series temperature transmitter is a kind of high precision, wide application range, direct output two-wire 4-20mA standard current signal, it is an industrial temperature measuring instrument with excellent cost performance.
The electrical housing of the RZ13 adopts a fully waterproof stainless steel. This ultra-micro structure integrated with a strong anti-interference signal conditioning circuit can reliably measure temperature for big vibration environment with strong reliability.
The RZ13 temperature transmitter uses high-reliability and long-life imported Class A PT100 or thermocouple as the temperature sensing element. The packaging structure adopts a compact integrated structure in which the sensor and circuit are packaged in the one shell; the signal processing adopts a linearity better than 0.01%, extremely stable and efficient electronic adjustment technology; through the internal potentiometer, the zero point and range can be accurately adjusted.
RZ13 integrates sophisticated sensor components, excellent circuit technology, and advanced packaging manufacturing technology. It is an ideal product for medium-precision temperature measurement and control in various industrial and mining fields.
