Page 6: Product Description
3 Product Description General The HTP501 is a robust probe for humidity and temperature measurement in air and other non-explosive gases. It features a humidity measuring range of 0...100 %RH and a temperature measuring range of -40...+120 °C (-40...+248 °F). The probe calculates all humidity-related quantities. Type T10 ist designed for pressure-tight installation from 0.01 (0.15 psi) up to 20 bar (290 psi). -

The manufacturer cannot be held responsible for personal injuries or damage to property as a result of incorrect handling, installation, wiring, power supply and maintenance of the device. The relations of electrical potential between a bus system and an HTP501 probe are characterized by the following properties: ▪... -
Page 8: Mounting And Installation
In such a case, the HTP501 may be for instance fixed onto a wall with the stainless steel mounting clip HA010225 (not included in the scope of supply, see data sheet “Accessories”), or freely hang from the ceiling on the connection cable. -
Page 9: Duct Mount
Working with pressurised pipes poses a considerable risk of injury and damage to property. When installing a HTP501-T4 in a pressurised system, precautions must be taken to prevent the sensor from shooting out. The internal feed-through (to the electronics) is suitable for up to 20 bar (290 psi). The actual working pressure (<20 bar (<290 psi)) will be determined by the choice of feed-through. - Page 10 Re-mounting: ▪ Slide the measurement probe with clamping ring into the fitting as far as it goes. ▪ Tighten the nut finger-tight, then tighten by approx. a ¼ turn using a spanner.
