MGL LM335 temperature sensors. Choose either the basic sensor or the one with aluminium cover.

These two OAT sensors use the LM335 semiconductor. 

The basic black sender is the ambient temperature probe included as standard with all our instruments that support ambient temperature measurements.

The OAT sensor with aluminium cover is a good looking option if you want to mount the sensor on the outside of the aircraft. The sensor is mounted in an 8mm hole and the unit comes with a nylon retaining nut and two nylon washers. 

This basic sensor is also a popular choice if you need to make your own coolant or oil temperature probes. In this case you use the brass body of an existing probe that fits your engine's requirements. Open, or drill out this probe and remove everything that is inside (so you end up with an empty brass body with the correct dimensions and thread). Then insert the sensor tip and ensure that the body of the tip contacts the brass body (to ensure rapid temperature transfer ). Then use a oil resistant epoxy to seal the sensor inside the brass body.

Red wire goes to instrument, green to ground.

We ship worldwide. At checkout you can choose from low cost airmail options and express courier services like DHL or FedEx.

Within the UK we normally dispatch using Royal Mail or DHL. You choose the level of service at checkout.

VAT sales tax (20%) is included in the price displayed on the website. This tax applies to UK customers and EU customers. It will continue to apply to customers in the 27 EU member states from 1 January 2021. This is because we are located in Northern Ireland. The Northern Ireland Protocol, agreed by the EU to facilitate cross border trade with the Irish Republic after Brexit, also applies to the rest of the EU.  We continue to charge the UK rate of vat to customers in the 27 EU member states and there is no further tax to pay upon delivery. We can continue to zero rate the vat for EU business customers who enter their vat number at checkout. 

Customers outside the EU do not pay vat and the tax will be removed at checkout. Local import taxes may apply - check with your local authority.

Currency. All products are priced in Pound Sterling (GBP, £). Using the "Currency" tab you can change the displayed currency to either Euro (EUR, €) or US Dollar (USD, $). This is an indicative exchange rate, automatically updated daily and is based upon the prevailing bank rate. The price you see may be displayed in USD or EUR but payment processing will be conducted in GBP. This means that your card issuer will apply their usual exchange rate, which is likely to be different from our indicative rate.

  EU Customers - NO TAX or CHARGES on delivery 

We are located in Northern Ireland and will continue to export under EU Customs Rules (unlike companies in the rest of the UK). Nothing changes because of Brexit. You continue to pay the vat inclusive prices on our website and you will not pay any tax or tariffs upon delivery. Businesses in the EU can enter their vat number at checkout and we will zero rate the sale. 

And of course, there is no change for our customers throughout the United Kingdom.
