Pipe Sensor With LED Readout

The LED option adds a high intensity red LED digital indicator to our pipe sensor for displaying local temperatures. This can be very useful in retrofit work when glass thermometer wells are re-used for HVAC sensors. Previously it was either expensive or impractical to shut down a section of the physical plant while a an extra well was welded in.

Now we have combined two sensors in the same sheath one connected to the indicator and one thermistor or RTD of your choice to connect to the control panel. An RTD can optionally be connected to a 4-20mA transmitter located in the same housing.

Jumpers on the circuit board permit field changes from Fahrenheit to Celsius and permit the 10ths of a degree indication to be converted to full degrees only.

An inexpensive option adds a setpoint alarm which can switch a one amp AC load.
Matched Pairs: On request 1/3 DIN RTD’s provide 1/10th deg C accuracy for energy consumption calculations.

Copper Averaging Probe

Our Copper Averaging Probe is constructed with a rugged bendable copper 1/4" O.D. tube.

Inside the Copper Averaging Probe numerous sensors are encapsulated at equal distances along the length of the sheath. The complete assembly acts as a single temperature sensor and any temperature change is averaged across the sensors. The Copper Averaging Probe can easily be bent to fit any size duct.

The rigidity of the copper tube may make it easier to install in applications where the sensor must be fed through a thick wall. It is somewhat more expensive than our Flex-Cable Averaging Sensor which has the same function.

Flex-Cable Averaging Sensor

Our probe is constructed using CSA rated FT6 plenum cable. Numerous sensors are encapsulated in 316 s/s sheaths at equal distances along the length of the cable. The complete assembly acts as a single temperature sensor and any temperature change is averaged across the sensors. The probe can easily be strung to fit any size duct.

For lengths up to 12 feet or for most economical applications, we average the readings of four encapsulated sensors. For 24 foot probes and more demanding applications, we use nine sensors spaced along the length of the cable.

Our moulded case with hinged cover is easy to install. The cover is fastened with one captive screw. Provision is made for a front identification tag. The back is completely smooth so it fits flush against the mounting surface. Circuit board slots inside are designed to accept a 2-wire transmitter if required.

Outdoor Weather Proof Air Temperature Sensors

Our outdoor air temperature sensors contain a rugged RTD or thermistor sensor for high accuracy and long term stability for temperatures between -50C to +80C or a thermistor for ease of connection to certain control systems. This assembly's construction consists of a waterproof seal, a weather resistant shield and non-corrosive material to withstand all weather conditions. The cover of the sensor rejects solar heat for more accurate temperature measurements. The sensor has a 1/2" NPT female thread for conduit mounting or clamp-on installation.

Plate Air Temperature Sensors

Our plate air temperature sensors are ideal for public or high traffic areas where a conventional space sensor could be easily damaged. The flush mounting eliminates accidental damage from knocks by machinery or people. The plain cover makes it unattractive to vandals since its function is not obvious. The stainless steel face reflects radiant heat while the sensor mounted in contact with the back of the plate provides fast, accurate space temperature readings. An adhesive foam backing secures the sensor to the plate and provides some insulation from temperatures inside the mounting wall. If mounting this sensor on an outside wall or one with a temperature that could be different than the surrounding space the installer should add sufficient insulation behind the sensor to ensure accurate space temperature readings.

Flue Gas Temperature Transmitters

Our flue gas temperature transmitters are constructed using the same technique we use in the industrial sensors we supply to power plants and heavy industries. The RTD or thermocouple is embedded in magnesium oxide, packed and sealed within a stainless steel sheath.

Because the sensor is so well protected from shock in this construction, long life is ensured, even under the most severe conditions. We incorporate a flange in our standard design in order to make mounting easy.

The terminal box containing the transmitter electronics is mounted on a stand-off to minimize heat transfer from the flue gas to the electronics.

The electronics convert the sensor signal to a standard 4 to 20mA 2-wire signal, for simple, economical and reliable wiring over long transmission lines.

Strap-On Temperature Sensors

We have engineered our strap-on sensors to ensure long life and rapid response. The sensor is mounted using PC board technology to eliminate strain on the sensor leads, increasing reliability. This assembly is potted in heat transfer compound to provide rapid response and cushion the sensor from vibration. The eight foot PVC lead wire makes it convenient to connect to a nearby utility box.

Brass Plate Temperature Sensors

When you need to measure the temperature of a pipe’s contents and no thermowell is available this is the solution. Simply add a little heat transfer paste to the smooth side of the brass plate and fasten the assembly to the pipe with a hose clamp. The 9 thou thick brass shim stock plate conforms readily to even small diameter pipes. Then cover the whole assembly with insulation, running the lead wire to a nearby junction box.

The brass plate will provide excellent heat transfer from the pipe to the sensor sheath which we silver solder to the plate. The 3/16" OD sheath is smaller than our normal strap on sensor to promote rapid heat transfer.

Soil Temperature Sensors

We have engineered our greenhouse soil temperature probe to ensure long life, rapid response and to seal against moisture.

The sensor is mounted using PC board technology to eliminate strain on the sensor leads, increasing reliability. This assembly is potted in heat transfer compound to provide rapid response and protection from vibration. The cover of our moulded case is gasketed to eliminate moisture problems. The stainless steel sensing probe is sealed by an O-ring where it joins the case.

The lead wires are attached to a terminal strip inside the case and exit the case through a moisture sealing strain relief fitting. Should the leads ever become damaged they can be changed without changing the sensor. Hundreds of these probes have been installed in greenhouses with excellent reliability.
