Assembly and Testing

At Boiswood we stock a wide variety of components to assemble Pressure Reducing and Back Pressure regulators. From the GO product range we can generally assemble the PR1, PR2, PR7, PR50, BP3, BP8 and BP60 models to your required specification from stock.

We would then pressure test the assembled regulators using our Nitrogen gas bottle to ensure they are functioning correctly. We can provide a copy of the pressure test certification on request.

With this considered, it means you could have your regulators assembled, tested and despatched on a next-day service, after the processing of your order.

Servicing and Repairs

In order to comply with the BCGA's recommendations of servicing/replacing regulators after a 5-year operation period, many users call on Boiswood to service their GO regulators.

Whether you require repairs for a faulty/broken regulator or just a general service - We will quickly turnaround a detailed corrective action report and recommendation for any spare parts. We can help to diagnose the causes as to why the regulator may have failed in service, always with the objective in mind of lowering your costs.

Again all regulators are assembled and pressure tested before they are returned to you.

Subassembly Design & Construction 

We will work closely with you to provide component subassembly and panel solutions suitable for your application.

Looking at the example to the left, we will take your required specification and produce a solution for you to sign off on. From there we can gather all of the necessary components and begin to create a suitable subassembly for your application.

Whatever your requirements contact us today for technical consultation.

1. Electro-Optic
The electro-optic type level sensors utilise their infrared LED light and receiver to detect. The LED is positioned and directed into a prism which forms the tip of the sensor. As soon as the media (liquid) touches the prism, it disrupts the light and senses the change. This change  can relay to an electronic switch (ie. actuating an alarm or circuit). 

2. Ultrasonic
The ultrasonic type level sensors have no moving parts and require absolutely no maintenance.  It offers an alternative to the generic reed switches and are ideal for applications where foam and condensation could affect the sensor. The ultrasonic pulses emitted reflect off liquid surfaces and the gap area therefore detects its presence or absence.

Sinking and sourcing are terms used to describe how a load (the device being turned on or off) is powered in regards to the sensor.

Sinking is the most common and it involves the switching of load current (power) supplied by a power source external to the sensor. With this configuration, current passes through the load first, through the output switch of the sensor second and finally to ground. Sensors with sinking output switches the negative leg of the circuit.

Sourcing refers to a configuration in which the sensor is the source of the current required to power the load. In a sourcing situation, current supplied by the sensor passes through the load second and then to ground. Sensors with sourcing output switches the positive leg of the circuit.
