Series 100 Hazardous

Traditionally HNL pressure switches have been designed to set an industry standard and not simply to meet a price. With the Series 100 range we give you the best of both worlds - the high accuracy, tight resets and reliability you have come to expect from HNL teamed with a competitively priced low unit cost.

Series 100 is both lightweight and compact - ideal for close panel mounting or OEM applications where space and weight is often restricted.

Series 100 Switches offer a wide selection of setpoint ranges with switching points from 100 mBar to 600 Bar. Stainless steel and Hastelloy C wetted parts are standard.

These compact switches are simple to install and maintain with end user installation and maintenance instructions available in clearly defined steps and supported by 3-dimensional exploded diagrams.

There are no covers to remove to adjust the setpoint; access to the setpoint adjustment screw is via the plugged hole at the top of the switch and is made using a standard 3mm allen key.

Output switches are certified EExd IIC T6 to standards EN 50014:1977 & EN 50018:1977.

Parameter definitions in accordance with BS6134:1991 (Pressure & Vacuum switches).

CE : This product satisfies the requirements of the Electromagnetic Compatibility Directive 89/336/EEC and amendments by compliance with standards EN50081-2:1993 and EN50082-2:1995. This product also complies with standard EN60947-5-1:1991 in addition to the standards listed for hazardous area certification.
