These thermostats are for duct applications and incorporate<br />
a single pole double throw contact switch.<br />
FEATURES<br />
• Simple installation and commissioning<br />
• Cable gland supplied<br />
The SPA 1501…1504 Differential Pressure Switches can be<br />
used to signal when the pressure difference is too high due<br />
to a blocked filter, too low due to flow failure, or for level<br />
control in a pressurised vessel. Suitable for use on a vacuum.<br />
The SPA 15<strong>05</strong> &1506 Pressure Switches can be wired into<br />
control circuits or contactors to provide a high or low<br />
pressure cut-out. Alternatively, they can be wired directly to<br />
a bell or light to provide a high or low pressure alarm. Not<br />
suitable for use on a vacuum.<br />
This switch is designed to control air flow using a paddle to<br />
switch on and off the power supply. The paddle can be<br />
trimmed if the air flow is above 5 metres per second.<br />
The SPA Differential Pressure Switch is used to monitor<br />
non-inflammable and non-aggressive gases. Typical<br />
applications are filter dirty and fan run/stop detection.<br />
ACCESSORY DDP 3601 Fitting Kit (containing 2 metres of<br />
PVC tubing and 2 duct mounting pitot tubes)<br />
The SFW Flow Switch is designed to control water flow, in<br />
pipe diameters from 1” to 6”, using a paddle to switch on<br />
and off the power supply. The paddle can be trimmed to<br />
suit the flow required. It is designed to be mounted in a<br />
short necked welded socket or a tee with a short branch.<br />
The TWK Thermostat is for water applications and<br />
incorporate a single pole double throw contact switch.<br />
FEATURES<br />
• Simple installation and commissioning<br />
• Cable gland supplied<br />
These thermostats are typically used in water high<br />
limit/control applications such as HWS cylinders or boilers.<br />
The TWL is a manual reset, high limit thermostat with a<br />
Single Pole Double Throw (SPDT) action. The TWM is a<br />
combined control thermostat and manual reset, high limit<br />
thermostat allowing independent setting of both the control<br />
point and high limit temperature.<br />
FEATURES<br />
• Simple installation and commissioning<br />
• Cable gland supplied<br />
• Manual reset<br />
• Concealed setting for reset temperature<br />
