Fine Controls supply a wide range of Temperature Probes and Temperature Transmitters to suit your application.
Fabricated or Mineral Insulated assemblies are available with a choice of Connection heads, sheath materials, with or without Thermowells. Temperature probes and temperature transmitters are available with Thermocouple or RTD sensors.
A thermocouple is a junction of two dissimilar materials which when joined at both ends with an indicating meter connected in one wire, will cause an electromotive force (emf) to register if the temperature of the two ends are different.
There are various types of temperature sensors and thermocouples available
covering the range -250°C
to + 3000°C RTD’s are usually chosen where better accuracy and
stability is required.
There is a wide choice of connection heads available including:
SCH4 = ABS plastic, IP67)
KNE = (die-cast alloy, IP65)
BUZ = (aluminium alloy, hinged flip cap)
A range of in-head temperature transmitters are available designed to accept either thermocouple or Pt100 inputs and provide a 4-20ma output
SEM203 = Push button programmable temperature transmitter
SEM205P = Smart Pt100 temperature transmitter
SEM310 = HART Universal Temperature Transmitter
Our range of RH and temperature transmitters are ideal for monitoring heat and humidity changes in weather & climate, and also provide transmission of these heat & humidity changes.
Some Temperature probes / temperature Transmitters can be fitted directly into the process by using an appropriate fitting. Other applications require a Pocket or Thermowell which is permanently fixed into the process and allows the temperature probe or temperature transmitter to be removed without disruption to the process. Various styles are available including screwed bsp or flanged, fabricated or solid turned.
In general RTD’s can be relied upon to remain within calibration for longer periods than thermocouples. RTD’s need to be calibrated perhaps once per year or more frequent when greater accuracy measurement is required
We recommend that thermocouples are calibrated every 6 months to one year.
