GUARDIAN INDUSTRIAL & ATEX SWITCHES

The Guardian pressure, differential pressure, temperature, level and flow switches are a part of our extensive range of specialist process sensors. They utilise the expertise gained from over 50 years experience of designing and manufacturing control devices for industrial, marine and hazardous area applications.

These switches are constructed with either a robust aluminium or stainless steel enclosure. The aluminium casting is black anodised and supplied with 316 stainless steel covers. The stainless steel case is a natural finish. Covers are gasketted and sealed to achieve an environmental seal to IP66 & IP67 standards. The internals utilise a unique mechanism designed by the engineers at PYROPRESS to produce a wide range, low switching differential and excellent repeatability. This combined with a variety of microswitches, mountings and sensor options has produced a switch range suitable for all weatherproof and intrinsically safe applications.

INTRODUCTION

The design features a simple form of calibration adjustment against a scale plate. This allows users to either order units with a specific setting, or stock a mid range setting and then calibrate to suit the application. Calibration is performed on the opposite side of the switch to the electrical connections, and can be set safely with the switch supply live. On removal of the adjustment cover a small grub screw can be loosened allowing the adjusting ring to be turned with a small Tommy bar or Allen key. The setting is read from the centre of the red indicating ring against the calibrated scale plate.

Calibration procedures for dual microswitches and adjustable switching differential switches are detailed on the operating and maintenance instructions supplied with each switch.

CALIBRATION

Our products are designed to work in demanding and hazardous environments which require fast and cost effective solutions in instrumentation

and control. Pyropress control sensors provide safe and

reliable electrical switching of alarm or control circuits in response to changes in temperature, pressure, differential

pressure,vacuum, fluid, flow and level conditions.

ABOUTPYROPRESS QUALITY

To support the design of state of the art products the company has invested heavily in the latest CNC technology.

We are able to produce our own components to a high degree of aaccuracy assuring a reliable and

consistent quality product.

Electrical Connections: Screwed terminals direct onto microswitch, suitable for cable up to 2.5 mm2. (Manual reset microswitch is supplied with 6BA solder tags).

Electrical Conduit Entry: M20 x 1.5 straight entry. Adaptors are available.

Environmental Protection: Switches have been tested and certified by an external test house to IP66 in accordance with BS EN 60529 : 1992. In addition further internal tests confirm that the switchcase meets the requirements of IP67.

Vibration and shock parameters: Switches were subjected to Lloyds Register Type Approval System Test Specification No.1 Clause 12 or 13 Vibration Test 1 or 2 (refer to sales for exact specifications) and shock tested to BS EN 60068-2-27 : 1987.

Temperature Limitations: Pressure, Vacuum and Differential Pressure.

Process: Diaphragm actuated (unless otherwise stated) -30 to +110˚C (Nitrile) or -20 to +150˚C (Viton). Piston actuated -30 to +120˚C (Nitrile), or -20 to +150˚C (Viton) or -50 to +150˚C (PTFE) -30 to 125˚C (EPDM)

Ambient: -25 to +80 Deg.C.

Storage: -25 to +80˚C. (For temp, level and flow refer to specific pages).

Certification: All switches are CE certified and marked in accordance with the following EU directives. Industrial : 2006/95/EC (Low Voltage Directive).

Exia: 94/9/EC ATEX coded CE Ex II1G Exia IIC. CAT 1 (Zone 0) areas. Special conditions for safe use. (Category 1, Zone 0) Aluminium may only be used when the ignition hazardous assessment shows that there is not risk of ignition from incendive, impact or abrasion sparks.

EXAMPLE. Dual microswitches - if switch 1 is set at 10 Bar on a 4 - 12 Bar range switch 2 can be set at the same pressure or between 10.2 and 12.0 Bar with standard adjuster and between 10.7 and 14.5 bar with secondary adjuster. With the second-ary adjuster fitted microswitches cannot be set together.Note: 1) Lowest set point is always switch 1 on dual set point switches. 2) Adjustable deadband mechanism actuates on falling settings, therefore reset on rising pressure.

GUARDIAN LOW PRESSURE

This range of switches employs a non-reinforced elastomer sensing element for settings between 8 and 250 mBar. A special feature of the Guardian switch is the wide selection of microswitches that can be fitted eg. single, dual, adjustable dead band, high current DC switching options etc. Reliable and proven design concepts from our established range of switches have also been incorporated. This provides a very competitively priced, lightweight and durable sensor.

GUARDIAN VERTICAL MOUNTING

These liquid level switches are designed to give indication or pump control of levels in tanks, vessels or sumps. The float travels unrestricted up or down the rod in response to level change between limits set by the upper and lower adjustable collars which are fixed in position at preselected points. This action operates an SPCO/SPDT microswitch dependant on application.

GUARDIAN VERTICAL MOUNTING

This range of magnet operated reed switches are equipped with hermetically sealed reed contacts. The float is fitted with an annular magnet which moves freely between two collars to open or close the reed contacts. As standard all wetted parts are 316 stainless steel, however they can be manufactured from different materials to suit a vast range of applications.

GUARDIAN HORIZONTAL MOUNTING

These liquid level switches are designed to give indication of high or low level alarms in tanks or vessels. They are fitted with a round or cylindrical float, the movement of which operates an SPCO microswitch via an offset pivot and push rod. A second microswitch can be fitted to give an additional signal.

The switch can be installed either via a 27mm clearance hole, utilising the joint washer and back nut supplied, and the float re-attached to the rod. Where there is no access to the tank interior, the cylindrical float with 2”/50mm flange version enables installation without removing and re-attaching the float.
