Introduction

JC-CZ28 series is a silicon piezoresistive sensor based on MEMS technology. It is a high stability and high precision OEM pressure measuring sensor. The series is packaged by pressure chips from internationally renowned manufacturers. 2" clamp connector for front end, external pressure is transmitted to the sensitive component through 316L stainless steel diaphragm and internal filling silicone oil, which can be used to measure all pressure media compatible with 316L stainless steel.
Each sensor was strictly temperature compensated for both zero and span.
It provides two power supply options: constant current and constant voltage.

* Measure corrosive media (compatible with 316L)
* Typical output：0-100Mv

Application

* Process control
* Fresh and waste water measurements
* Medical and food instruments
* Pressure transmitters
* Level measurement

Remark
1. Best fit straight line.
2. The pressure sensor performs the pressure from the minimum value to the maximum value (positive stroke) and the maximum value to the minimum value (reverse stroke), and the deviation of the output value at any pressure within the pressure range from the forward stroke to the reverse stroke;
3. In the same test method as in 2, perform 3 forward and reverse stroke pressure cycles;
4. Compared with the output of 25 °C in the compensation temperature range
5. Zero output is the deviation value before and after the sensor performs a temperature cycle of -40~+125°C.
6. Increase the load resistance to reduce the measurement error
7. Between the lead and the outer casing

Note:
Food grade oil-filled sensors are also available and need to be customized
1. Can be used for down-range, and the amplitude is controlled within ±50%FS.
2. The maximum pressure of the system should be less than the overload protection limit of the sensor, otherwise it will affect the service life of the product and damage the product.
3. The commonly used compensation method for products is 1.5mA constant current compensation.
4. Do not force to pull the pins or the leads of sensitive components.
5. Protect the isolation diaphragm at the front end of the pressure sensitive component to prevent the impact of the pressure sensitive component from damaging the sensitive component.
