Product Overview JC660 series of anti-explosion pressure transducer is specially designed for high-explosion dangerous site. It can provide stable and accurate measurement at an absolute pressure, gauge pressure and differential pressure of liquid or gas medium from -100KPa to 200MPa. It welds the existing multi -crystalline silicon film sensing element with the enclosure using welding technology and can be customized rapidly according to the regulations to meet the individualized needs of different users. With built-in amplification circuit and diversified structural forms, it can be equipped with M 20 x 1.5 or G1 / 2 internal thread explosion-proof flexible tube connector. Featured by good performance, small size and flexible design, JC660 series anti-explosion pressure transducer has the advantages of a very high ratio of performance to cost and long service life compared with traditional explosion-proof transducers. It is widely used in oilfield, mining well, chemical, electric power, boiler, natural gas and other fields.
JC660 - E type pressure transducer is an intrinsically safe explosion-proof pressure transducer, with explosion- proof marking of Ex iaII CT6 and explosion-proof conformity certificate number of CNEx07.0988. It boasts stable and reliable performance supporting the use of repetitive-use type safety energy limiter or safety barrier.
JC660 - D type pressure transducer is a flameproof pressure transducer, with explosion - proof marking of Ex d IICT6 and explosion-proof conformity certificate number of CNEx08.2405.
JC660 - ED type is an intrinsically safe flameproof pressure transducer, with explosion -proof marking of Ex ia II CT6 and Ex d II CT6. It is safe and reliable and simple and convenient to operate, without the installation of safety barrier when installed and used.

Tips of Selection- The measured medium shall be compatible with the material contacting with the product.
- The code E, an additional function code for selection, namely, intrinsically safe explosion-proof Ex iaIICT6 must be power supplied via safety barrier.
- The code D, an additional functional code for selection, namely, flameproof Ex dIICT6 is preferably provided with explosion - proof flexible hose for the electrical power cable connected at the rear side.
- The options W1 and W2 are general structural encapsulation and only used for HM60 - E intrinsically safe explosion-proof pressure transducer.
- It is unnecessary to install safety barrier on JC660 - ED intrinsically safe flameproof pressure transducer during system use.
- Please contact us for other special requirements and clearly indicate them in the order.
