The RHA101 is a hygienic temperature assembly combining a spring loaded RTD sensor and solid drilled RJT thermowell. This heavy duty construction is designed for use within applications involving high pressures and flow rates.
The RHA101 temperature sensor is available as a 2, 3 or 4 wire Pt100 or Pt1000 in either simplex, duplex or triplex configuration. The accuracy class can be selected from 1/10 DIN, 1/5 DIN, 1/3 DIN, class A or class B.
This hygienic RTD assembly is available with an aluminium, stainless steel or plastic connection head which has a M20 x 1.5 cable entry. The sensor can be terminated with a ceramic terminal block, 4 to 20 mA transmitter or supplied with tails. There is also an option to specify loop powered or battery powered indicator.
The RHA101 hygienic thermowell is available with either a parallel or tapered stem profile and has wide variety of process thread connections available.
In order to determine or prove the suitability and required dimensions of a thermowell based on the process conditions, we offer wake frequency calculations as per ASME PTC 19.3 TW-2016. In addition there are a number of other certification and testing services available including 3.1 material certificates, pressure testing and positive material identification (PMI).
The RHA101 hygienic RTD temperature sensor is available with optional ATEX/IECEx Exia (intrinsically safe) and ATEX/IECEx Exd (flameproof) hazardous area approval for use within Zones 0, 1, 2, 20, 21 and 22.
