Q1: Is the MPS-71/74/78 still in production?
A: No. The series is discontinued and kept as technical reference for service and replacement.
Q2: What are the model differences?
A: MPS-71 = 1-channel, MPS-74 = 4-channel, MPS-78 = 8-channel central display/output.
Q3: Benefits of the remote head design?
A: Mount the sensor close to the measurement point while keeping the display on the panel—shorter wiring, lower noise, easier maintenance.
Q4: What is the protection rating?
A: IP40; not recommended for humid or dusty environments.
Q5: Recommended replacements?
A: Consider newer families such as MPS-42 (differential) or MPS-35 (dual-screen, tri-color) for improved performance and protection.
