Optional Thermowells
Murphy offers thermowells (separable sockets) to facilitate maintenance of a temperature Swichgage instrument and to protect the temperature sensing bulb from extreme amounts of sys- tem pressure. For system pressures exceeding 285 psi (1.97 MPa) [19.7 bar] at 625°F (329°C) an optional thermowell is recommended for use with the SDB series.
The thermowell protects the SDB bulb from system pressures up to 3000 psi (20.68 MPa) [206.8 bar] at 300°F (149°C). Two thermowell options are available: 1/2 NPT and 3/4 NPT. Thermowells can be ordered with the SDB Series Swichgage instrument or ordered separately.
