Transmitter
RZ23L Series Pressure Transmitter
Product Details
RZ23L series pressure transmitter is an industrial pressure measuring instrument with high accuracy, wide application range, and excellent cost performance.
RZ23L's pressure measurement sensitive components use metal isolation diaphragm structure diffused silicon piezoresistive or ceramic capacitor sensors; the packaging structure adopts a miniature integrated structure in which the sensor and circuit are packaged in the same stainless steel shell; the overall laser welding, signal processing adopts Specially stable, high efficiency, linearity better than 0.01% imported conditioning circuit technology, the product has passed strict testing and aging screening of components, semi-finished products and finished products. These conditions ensure that the transmitter has high accuracy, good stability, and strong anti-interference ability.
l Reverse polarity protection and instantaneous over-current and over-voltage protection, meeting EMI protection requirements;
l Through the internal potentiometer, the zero point and range can be accurately adjusted;
l The output signal has a variety of standard specifications such as: 4～20mA, Rs485 digital signal, HART protocol 4～20mA, can be connected to the display meter.
l Wide range of measurement.
l All stainless steel structure, various types of pressure ports, with flush membrane type, sanitary type, anti-corrosion type, etc., protection grade IP65.
