JC660 Anti-explosion Pressure Transducer

●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 of HELM 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 iaⅡCT6 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 dⅡCT6 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 iaⅡCT6 and Ex dⅡCT6. It is safe and reliable and simple and convenient to operate, without the installation of safety barrier when installed and used.

●Tips of Selection
1.The measured medium shall be compatible with the material contacting with the product.
2.The code E, an additional function code for selection, namely, intrinsically safe explosion-proof Ex iaIICT6 must be power supplied via safety barrier.
3.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.
4.The options W1 and W2 are general structural encapsulation and only used for HM60 – E intrinsically safe explosion-proof pressure transducer.
5.It is unnecessary to install safety barrier on HM60 – ED intrinsically safe flameproof pressure transducer during system use.
6.Please contact us for other special requirements and clearly indicate them in the order.
