Temperature Measurement Solutions:

Getting Ambient Temperature Measurements

Temperature Measurement Solutions:

Measuring ambient temperatures is a common application with a number of solutions depending upon your use of the word “ambient”.

Temperature Q&A with JR: We are seeing false readings in our outdoor temperature measurement application due to environmental exposure

Temperature Q&A with JR: We are seeing false readings in our outdoor temperature measurement application due to environmental exposure

Q: We have several outdoor temperature applications where we measure the temperatures of pipes running alongside cooling towers. These sensors are in several different locations and zip-tied to the outer surface of the cooling pipes. Our problem has been that exposure to rain, sun and heavy snow causes signals to drop off or spike. We believe moisture is getting into the wire jacket and the environmental exposure is causing false readings. The sensors we use have a PVC jacket over the lead wires and it shows cracking over time. We need to replace the sensors and would like a 4-20mA output signal to go from our junction box out to the field instead of running the sensor lead wires all the way back to our monitoring system. What type of solution do you have for this?

THZ3 & TDZ3 Smart HART Temperature Transmitter Replaces Retired THZ2 & TDZ2

THZ3 & TDZ3 Smart HART Temperature Transmitter Replaces Retired THZ2 & TDZ2

Moore Industries’ release of the THZand TDZ3, our next gen Smart HART temperature transmitters, officially replaced the retired THZand TDZ2 product lines. 

Moore Industries is no longer building or fulfilling orders placed for the THZand TDZ2, offering the THZ3 and TDZ3 in their place.

The 3rd generation temperature transmitters continue to offer our industry leading durability and reliability and introduce several new features that increase usability and functionality. The most significant feature is the new dual sensor input.

EHELP: Converting Three Analog Signals to HART Protocol

EHELP: Converting Three Analog Signals to HART Protocol

Q: You have a product called HART Interface Module that will pull the 2nd, 3rd and 4th HART variables from a smart HART transmitter and create one 4-20mA signal for each. Do you have or know of an instrument that will take three 4-20mA signals into it and place them on one 4-20mA signal as the 2nd, 3rd and 4th variable? I would like to read three transmitters on one 4-20mA signal by reading the variables on my DCS System.

Avoid Measurement Errors with Sensor Drift Detection

Avoid Measurement Errors with Sensor Drift Detection
Sensor drift is a common problem that can lead to inaccurate temperature measurement readings. It can be caused by several factors including environmental contamination, vibration or extreme temperature fluctuations. Because this drift causes the measurement error to get worse over time, it’s not possible to calibrate out the error. Traditionally, reducing inaccurate measurements caused by sensor drift has meant undertaking a regular and time-consuming preventative maintenance calibration program.
