Frequently Asked Questions

General FAQ’s

What mounting arrangements are available?

Our standard options are; 1-bolt, 2-bolt, 3-bolt, 5-bolt SAE, AN-8 threaded (9/16UNF) and AN-10 (3/4UNF). However, if these do not fit your requirements, please contact one of our engineers to discuss our wide range of custom flange arrangements.

Is the cable length configurable?

Yes. All of our sensors are made to order in-house so we manufacture the cable length to the customers specification.

Does it have to be red?

No, we can anodise the sensor in most colours. The lead time will increase and it will be subject to a small surcharge to cover the additional process.

What is the pressure rating?

All of our LS range of standard sensors have internal seals so they can safely operate in pressurised tanks. The sensors are tested to 2 Bar differential pressure (30psi) during manufacture, however the internal sealing have been tested to 10bar for short periods.

What is the maximum operating temperature?

We have three operating temperature standards, -40degC to +85degC, -40degC to +125degC and -40degC to +150degC.

What is the IP rating of the sensor?

As standard, the sensors have been designed for IP67, however we have customised solutions for up to IP69X.

Are your sensors suitable for ATEX approval?

Our core range and off-the-shelf products are not currently suitable for ATEX approval but a custom solution could be made available.

What are the available outputs?

Our sensors can be designed to deliver CAN or analog (0-5V) outputs.

Can the customer configure the sensor?

All our sensors are calibrated at the factory in the customer specified fluid so that they are plug and play on arrival. However we offer the GUI free of charge with the purchase of a Reventec comms module 07-009-01.

What warranty does Reventec offer?

We offer a 1 year warranty from date of delivery. For further details, please see our full terms and conditions available here.

What is a typical lead time for a standard sensor manufactured to a specific length?

Typical lead times for our standard products are 2 – 3 weeks, however we can offer expedited manufacture if required. Please talk to a Reventec Sales Representative for more information.

What is the lead time for a custom sensor?

We will work closely with the customer to formulate a specification and mechanical design. Following design approval, lead times are typically 4 – 6 weeks, subject to final specification and quotation.

Liquid Level Sensors FAQ’s

How close to the bottom of the tank can the sensor be mounted?

We recommend leaving a minimum gap of 3mm from the tip of the probe to the bottom of the tank. This is to allow the liquid to enter the sensor un-obstructed.

What is the shortest length sensor available?

For continuous level measurement, the minimum sensor length we recommend is 80mm. If the sensor is shorter, the continuous measurement becomes more of a level switch.

What is the longest length sensor available?

For our standard LS range of Liquid Level Sensors, the maximum length is 750mm. However, with small modifications we can achieve a much longer sensor length, for example up to 3m in an existing application. Please contact our engineers to discuss deep tank applications.

Do you offer standard Liquid Level Sensor lengths?

All of our sensors are manufactured to your specified length requirement. We do hold stock of all of our flange designs, up to a probe length of 450mm, so short lead times are often available.

What does a typical sensor weigh?

Nominal weight for a 300mm sensor is <100g, including cable.

Can I have a short carbon fibre sensor?

Yes, for an additional cost we can add carbon fibre to any level sensor. The tube OD will increase to 14mm for standard sensor designs.

What is the returns procedure?

Please contact your Reventec sales representative for an RMA number. Detail the fault and they will be able to assist you directly.

Can I test my sensor using water?

Only if the sensor is calibrated for use with water or other polar liquids. Capacitive level sensors rely on the dielectric of the liquid they are expected to measure. Attempting to measure a liquid which the sensor is not calibrated for will result in incorrect readings from the device.

I have changed the fuel grade on my car, can I send the liquid level sensor back for recalibration?

Yes, for a small charge we can recalibrate any sensor to a new liquid grade, assuming the sensor is compatible with the new grade. If you are unsure, please contact a Reventec engineer to discuss your specific requirements.

Can the sensors be cut to length?

No. All sensors are manufactured in house to the customers specified length and we will work closely with the customer if lead time is critical to ensure timely delivery.

Position Sensors FAQ’s

What is the smallest size a position sensor can be?

Our position sensors can be packaged in an infinite number of shapes and sizes dependent on your requirement. As an example, the smallest measurement head is 5mm x 12mm, excluding conditioning electronics. Sensor sizes vary based on the number of channels/outputs required, voltage input, the required measurement length (which determines the number of measurement heads selected), and whether the processing electronics are integrated or remotely located. As an indication, we can manufacture sensors with 1-16 measurement heads and with voltage inputs from 5V to 40V.

What is the range of the sensor from the magnet target?

Our position sensors can measure across a 40mm air gap to target and sense through up to 20mm of non-ferrous material subject to the magnet specification.

What is the greatest distance you can measure across?

The largest Quantum TMR position stroke is up to 800mm.

What materials can your position sensors be packaged in?

Quantum TMR position sensors can be packaged in a variety of materials, including; all plastics, aluminium, stainless steel, titanium, brass and carbon fibre.

What is Quantum TMR technology?

Quantum TMR is Reventec’s position sensing technology. Harnessing both the power of Tunneling MagnetoResistance and quantum mechanics for accurate position measurement, this technology is capable of sensing through solid non-ferrous walls such as aluminium or stainless steel. For more information, please contact us.

What is the difference between Tunneling Magneto Resistive technology and Hall Effect sensors?

Both Hall Effect sensors and Tunneling MagnetoResistance sensors use a magnetic field to determine position from sensor to magnet target. The benefits of Tunneling MagnetoResistance sensors are that they have superior field sensitivity (typically over 1000 times that of a standard Hall effect sensor).  TMR technology measures the flux field angles using sines and cosines to determine position whilst Hall effect use magnetic field strength.

Temperature Sensors FAQ’s

What output options are available?

Available output options for our range of temperature sensors include: Resistive PT1000, Analog (customisable to the customers desired temperature range), and CAN 2.0. Please contact us if you require a different output format.

What are the operating temperature limits?

Our standard operating temperature ranges are:
Detector: -50°C to +250°C
Electronics:  -40°C to +150°C

Are custom mounting options available?

We have a number of standard options available as well as a large variety of customised options. Manufacturing small volumes for specific applications is available.

What is the IP rating?

We have manufactured temperature sensors previously that go beyond IP rating standards, where high temperature submersible specifications are required. As standard, our sensors offer IP67.

What is the maximum probe length?

We have manufactured temperature probes up to 3m in length.
