On Request. Please send us an email to inquire the price and avaliability.
"ucnguBrctvdgcxgt0eqo"
Description
Simple switch point setting by means of two setting rings allowing optimum reading. High long-term stability thanks to robust stainless steel measuring cell with high permissible pressure rating. Mechanical locking prevents inadvertent switch point manipulation. Lifespan of more than 50 million pressure cycles. For use in hydraulics, pneumatics, air-conditioning and refrigeration
