Thermowells must be used on all pressure or velocity applications, to protect the stem of thermometer from corrosion and physical damage, and to facilitate removal of the thermometer without disturbing the process. Maximum ambient temperature is 200ºF (95ºC).
Ashcroft offers three types of thermometers: bimetal thermometers, gas-actuated Duratemp® thermometers and digital thermometers. The bimetal thermometer measures ranges from -80° F to 1000°. The gas-actuated Duratemp® series measures temperatures from -320° F to 1200° F. The digital thermometer is panel mounted, shock and vibration resistant and comes in a watertight ultrasonic sealed case. Also available is a line of thermowells designed to work with Ashcroft industrial temperature instruments. Thermowells come in 304 stainless steel and 316 stainless steel with available .260 and .385 bore size. Reliable and accurate, Ashcroft temperature measurement instruments are ideal for use in a wide variety of industrial measurement and monitoring applications.
Digital Thermometer Type 2400E and 2410E Accuracy (±2° NSF per C-2)
The Ashcroft® 2400E and 2410E digital thermometers are compact, solid state temperature measurement and display devices. The 2400E measures temperature with a laser-trimmed 2000 ohm RTD contained in a stainless steel probe. The signal from the RTD is conditioned and sent through an analog-to-digital converter and is shown on a LED display.
The unit is powered by 6 Vdc, which is delivered through a power supply that operates on 110 Vac (220 Vac and 24 Vac are optional). When more than one indicator is required, two thermometers can be operated by one 110 Vac supply. The power supply is UL recognized and the complete unit is NSF approved for class C-2 applications.
